CLI/Reduce.cpp:
Never worked under MinGW as-is. Add check for MinGW as they're defined.
VM/src/lmem.cpp:
MinGW layout follows more closely MSVC. Checks before were only correct
for 32-bit gcc / clang in non-Windows.
NOTES:
__MINGW32__ is defined on both 32-bit and 64-bit, __MINGW64__ is 64-bit
only. 32-bit MinGW compilers (both Clang & GCC) have a floating point
test error on math.noise, specifically math.lua:258. All other test
cases / unit tests pass modulo stack size issues (so requires optimized build).

- TableOperations lint now includes a warning for table.create(N, {}) (which is likely a mistake since the table is shared by all entries)
- Type checker now type checks #v when v is a union
- Parser now rejects sources that consists of a single unfinished long comment
- Work around significant MSVC 2022 performance regression, bringing it more or less in line with MSVC 2019
- Compiler now predicts array size for newly allocated tables when the table is filled in a short loop
- Small improvements in compilation throughput (~2% faster)
- Implement paged sweeper for GC which improves sweep throughput 2-3x and reduces memory consumption by 8 bytes per object (once it is stabilized we will see additional 8 bytes per object of savings)
- Improve Repl Tab completion
- Repl now supports -i (interactive mode to run code in context of a script's environment) and -On (to control optimization flags)
- A series of major optimizations to type checking performance on complex
programs/types (up to two orders of magnitude speedup for programs
involving huge tagged unions)
- Fix a few issues encountered by UBSAN (and maybe fix s390x builds)
- Fix gcc-11 test builds
- Fix a rare corner case where luau_load wouldn't wake inactive threads
which could result in a use-after-free due to GC
- Fix CLI crash when error object that's not a string escapes to top level
- Fix Makefile suffixes on macOS
