As discussed in the issue, Luau has evolved from Lua to the point
where a new default extension `.luau` would be needed.
This change makes the REPL and Analyze look for `.luau`
extension first and if not found, fall back to `.lua`.
Right now our CMake infra specifies -Wno-unused only for GCC builds, but Makefile specifies it for all builds.
The intent has been to use it just for GCC, so we now do that by detecting the compiler version - this should
equalize the behavior across different types of builds.
Separately, latest version of clang appears to expose an unused variable that clang-10 was okay with, so fix that. (change from upstream)
- 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

Changes:
- Support for time tracing for analysis/compiler (not currently exposed
through CLI)
- Support for type pack arguments in type aliases (#83)
- Basic support for require(path) in luau-analyze
- Add a lint warning for table.move with 0 index as part of
TableOperation lint
- Remove last STL dependency from Luau.VM
- Minor VS2022 performance tuning

When running `luau-analyze` with a .luarc that has a "mode" key, it outputs the following:
> .luaurc: Unknown key mode
I'm assuming it was named "mode" at first and was re-named "languageMode" later on?
Full documentation for the standard library, written from scratch by looking at the source code - so hopefully this is reasonably correct/precise.
Some of the function descriptions are probably too concise to be easily understandable - we can flesh this out in the future.
Some of the type specifications aren't using valid Luau syntax; in particular, I've used "function" or "table" in a few places as a human-friendly notion that any function/table suffices, and the iterator functions just say that they return <iterator> without being specific as to what the signature of the generator is.
* RFC: Default type alias type parameters
* Update the motivating example to match actual motivating example
* Resolved review comments
* improved motivation for the feature and noted additional languages with this feature
* fixed terminology between 'argument' and 'parameter'
* brought back support for default type pack parameter values
* removed alternative syntax and described the decision between ':' and '=' in the design section
* fixed drawback text and provided an example
* Remove return type pack annotation from allowed type pack default values,type annotation syntax doesn't allow that to be stand-alone
* Generic type pack has to be referenced by generic type pack name (with ...)
A large number of changes to the HATRA '21 position paper. We've abandoned the 4pp limit, which allows us to add more detail to some sections, and use more appropriate wording throughout the paper. A rough changelog:
* Numerous wording tweaks
* Removed `\cite{???}`
* Added type inference section
* Introduction beefed up
* Abstract slightly tweaked
