Add SUBRK and DIVRK bytecode instructions to bytecode v5 (#1115)
Right now, we can compile R\*K for all arithmetic instructions, but K\*R
gets compiled into two instructions (LOADN/LOADK + arithmetic opcode).

This is problematic since it leads to reduced performance for some code.
However, we'd like to avoid adding reverse variants of ADDK et al for
all opcodes to avoid the increase in I$ footprint for interpreter.

Looking at the arithmetic instructions, % and // don't have interesting
use cases for K\*V; ^ is sometimes used with constant on the left hand
side but this would need to call pow() by necessity in all cases so it
would be slow regardless of the dispatch overhead. This leaves the four
basic arithmetic operations.

For + and \*, we can implement a compiler-side optimization in the
future that transforms K\*R to R\*K automatically. This could either be
done unconditionally at -O2, or conditionally based on the type of the
value (driven by type annotations / inference) -- this technically
changes behavior in presence of metamethods, although it might be
sensible to just always do this because non-commutative +/* are evil.

However, for - and / it is impossible for the compiler to optimize this
in the future, so we need dedicated opcodes. This only increases the
interpreter size by ~300 bytes (~1.5%) on X64.

This makes spectral-norm and math-partial-sums 6% faster; maybe more
importantly, voxelgen gets 1.5% faster (so this change does have
real-world impact).

To avoid the proliferation of bytecode versions this change piggybacks
on the bytecode version bump that was just made in 604 for vector
constants; we would still be able to enable these independently but
we'll consider v5 complete when both are enabled.

Use ubuntu-latest on GHA when possible (#1112)
We need ubuntu-20.04 for coverage analysis (clang after 10 doesn't seem
to properly interact with gcov version used for codecov) and for
releases (to produce binaries targeting earlier glibc).

However, we still should be verifying that Luau builds on latest,
because newer toolchains have stricter standard library headers and/or
warnings; without this we're at risk of constantly regressing the build
for packaging or external applications.

Note that release.yml can probably just be deleted but for now we simply
adjust it.

Include module name for definitions files (#861)
Closes #818 

We set the `moduleName` of the source module to the provided
`packageName`.
This then populates the relevant `definitionModuleName`'s on
CTV/FTV/TTVs, so it allows us to lookup where they originated from.

The one place I can see this having an impact inside of Luau code is the
following:

1fa8311a18/Analysis/src/Error.cpp (L70-L90)
Which will potentially change they way error messages are formatted.
Should there be a way to exclude definition files when calling
`getDefinitionModuleName`, so we can preserve this behaviour?

New Solver

* New algorithm for inferring the types of locals that have no
annotations. This
algorithm is very conservative by default, but is augmented with some
control
  flow awareness to handle most common scenarios.
* Fix bugs in type inference of tables
* Improve performance of by switching out standard C++ containers for
`DenseHashMap`
* Infrastructure to support clearer error messages in strict mode

Native Code Generation

* Fix a lowering issue with buffer.writeu8 and 0x80-0xff values: A
constant
  argument wasn't truncated to the target type range and that causes an
  assertion failure in `build.mov`.
* Store full lightuserdata value in loop iteration protocol lowering
* Add analysis to compute function bytecode distribution
* This includes a class to analyze the bytecode operator distribution
per
function and a CLI tool that produces a JSON report. See the new cmake
      target `Luau.Bytecode.CLI`

Optimize vector literals by storing them in the constant table (#1096)
With this optimization, built-in vector constructor calls with 3/4 arguments are detected by the compiler and turned into vector constants when the arguments are constant numbers.
Requires optimization level 2 because built-ins are not folded otherwise by the compiler.
Bytecode version is bumped because of the new constant type, but old bytecode versions can still be loaded.

The following synthetic benchmark shows ~6.6x improvement.
```
local v
for i = 1, 10000000 do
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
	v = vector(1, 2, 3)
end
```

Also tried a more real world scenario and could see a few percent improvement.

Added a new fast flag LuauVectorLiterals for enabling the feature.

# What's changed?

- Record the location of properties for table types (closes #802)
- Implement stricter UTF-8 validations as per the RFC
(https://github.com/luau-lang/rfcs/pull/1)
- Implement `buffer` as a new type in both the old and new solvers.
- Changed errors produced by some `buffer` builtins to be a bit more
generic to avoid platform-dependent error messages.
- Fixed a bug where `Unifier` would copy some persistent types, tripping
some internal assertions.
- Type checking rules on relational operators is now a little bit more
lax.
- Improve dead code elimination for some `if` statements with complex
always-false conditions

## New type solver

- Dataflow analysis now generates phi nodes on exit of branches.
- Dataflow analysis avoids producing a new definition for locals or
properties that are not owned by that loop.
- If a function parameter has been constrained to `never`, report errors
at all uses of that parameter within that function.
- Switch to using the new `Luau::Set` to replace `std::unordered_set` to
alleviate some poor allocation characteristics which was negatively
affecting overall performance.
- Subtyping can now report many failing reasons instead of just the
first one that we happened to find during the test.
- Subtyping now also report reasons for type pack mismatches.
- When visiting `if` statements or expressions, the resulting context
are the common terms in both branches.

## Native codegen

- Implement support for `buffer` builtins to its IR for x64 and A64.
- Optimized `table.insert` by not inserting a table barrier if it is
fastcalled with a constant.

# What's changed?

* Fixed a bug in type cloning by maintaining persistent types.
* We now parse imprecise integer literals to report the imprecision as a
warning to developers.
* Add a compiler flag to specify the name of the statistics output file.

### New type solver

* Renamed `ConstraintGraphBuilder` to `ConstraintGenerator`
* LValues now take into account the type being assigned during
constraint generation.
* Normalization performance has been improved by 33% by replacing the an
internal usage of `std::unordered_set` with `DenseHashMap`.
* Normalization now has a helper to identify types that are equivalent
to `unknown`, which is being used to fix some bugs in subtyping.
* Uses of the old unifier in the new type solver have been eliminated.
* Improved error explanations for subtyping errors in `TypeChecker2`.

### Native code generation

* Expanded some of the statistics recorded during compilation to include
the number of instructions and blocks.
* Introduce instruction and block count limiters for controlling what
bytecode is translated into native code.
* Implement code generation for byteswap instruction.

Record table type alias property locations (#1046)
For table type aliases, records the location of the property in the
alias declaration.

This is an alternate solution to the particular case noted in #802.
Instead of tracking the type alias definition for FTVs, it tracks it for
the encompassing property instead.

Note that we still don't have positions in the following case:

```
type Func = () -> ()
```

Closes #802 (Although not completely...)

Implement bit32.byteswap (#1075)
I've decided to take a stab at implementing `bit32.byteswap` from the
[recently merged
RFC](https://github.com/Roblox/luau/blob/master/rfcs/function-bit32-byteswap.md).
I asked on Discord for some guidance, but for the sake of posterity:
this is my first time doing this and I am likely to have made some
mistakes.

The biggest gaps in this implementation are the lack of tests and the
lack of native codegen support. I'd appreciate help with those since I'm
not sure what's relevant for me to touch for tests, and I'm told that
relevant assembler instructions don't exist publicly yet. Intuition
tells me that Luau-side tests would go into
`tests/conformance/bitwise.luau` but this is not well documented and I'm
not sure how I'm meant to test built-in implementations.

The current implementation compiles down to `bswap` and `rev` on x86 and
ARM respectively when optimized.

### What's Changed

- Improve readability of unions and intersections by limiting the number
of elements of those types that can be presented on a single line (gated
under `FFlag::LuauToStringSimpleCompositeTypesSingleLine`)
- Adds a new option to the compiler `--record-stats` to record and
output compilation statistics
- `if...then...else` expressions are now optimized into `AND/OR` form
when possible.

### VM

- Add a new `buffer` type to Luau based on the [buffer
RFC](https://github.com/Roblox/luau/pull/739) and additional C API
functions to work with it; this release does not include the library.
- Internal C API to work with string buffers has been updated to align
with Lua version more closely

### Native Codegen

- Added support for new X64 instruction (rev) and new A64 instruction
(bswap) in the assembler
- Simplified the way numerical loop condition is translated to IR

### New Type Solver

- Operator inference now handled by type families
- Created a new system called `Type Paths` to explain why subtyping
tests fail in order to improve the quality of error messages.
- Systematic changes to implement Data Flow analysis in the new solver
(`Breadcrumb` removed and replaced with `RefinementKey`)

Facelift of the Account OO example. (#578)
When the original version was written, bidirectional type inference
didn't exist, so this new kind of pattern was simply not possible.

Now that it does, we can stop telling users to use the original typeof
workaround.

The only thing that's a bit unfortunate is the cast of `{}` into
`AccountImpl`, but it's a necessary evil for now until we get a few more
big ticket items. When we have that, we can likely kill the cast and
call it redundant.

Add lua_getallocf API function (#1068)
This function matches the corresponding Lua 5.1-5.4 function:

[`lua_getallocf`](https://www.lua.org/manual/5.4/manual.html#lua_getallocf)
and [source](https://www.lua.org/source/5.4/lapi.c.html#lua_getallocf)

It would be useful to get/manipulate auxiliary "userdata" pointer that was originally passed to `lua_newstate`.

Modify the way line breaks are added when printing unions/intersections (#1047)
Adds an option `compositeTypesSingleLineLimit` to control when
unions/intersections are broken up onto multiple lines when printed.
Simple unions/intersections will remain on one line. Default value is
set to `5`.

I took the liberty to always expand overloaded function intersections on
multiple lines, as I believe they are best viewed that way, even if
theres only 2 functions.

Closes #963
