Another week, another release!
## Analysis
- Hide errors in all solver modes (not just strict mode) if the only
error is that type inference failed to complete.
- Make various analysis components solver-agnostic (`setType`, `visit`,
`Scope` methods).
- Fix an issue where type inference may fail to complete when assigning
a table's member to the table itself.
- Fix a bug when accessing a table member on a local after the local is
assigned to in an if-else block, loop, or other similar language
construct.
- Fixes#1914.
- Fix type-checking of if-then-else expressions.
- Fixes#1815.

# What's changed?
Another somewhat quiet week! Don't let the large PR fool you, this is
mostly ...
## New Solver
* The code for type functions has been re-organized: instead of
_everything_ living in `TypeFunction.h` and `TypeFunction.cpp`, we now
have separate files for the type function inference machinery
(`TypeFunction.h`), definitions of built-in type functions
(`BuiltinTypeFunctions.h`), and the implementation of user defined type
functions (`UserDefinedTypeFunction.h`).
* Refinements against `*no-refine*`, a sentinel type indicating that no
refinements should occur, are now _always_ resolved, even if the target
of the refinement would be otherwise pending, such as another type
function.
## Autocomplete
* Fixed autocomplete to prefer table property completion to string
singleton completion. In the below example, the types associated with
each member of `foo` will be displayed in autocomplete popups.
```
local foo = {
["Item/Foo"] = 42,
["Item/Bar"] = "it's true",
["Item/Baz"] = true,
}
foo["|"] -- cursor at `|`
```
## Native Codegen
* Fixed native compilation lowering of the new global lookup
instruction, which caused code generation to fail with an error or to
evaluate incorrect results. Issue affected 678-681 releases when all
flags were enabled.
