Sync to upstream/release/581 (#958)
* Definition files can now ascribe indexers to class types.
(https://github.com/Roblox/luau/pull/949)
* Remove --compile support from the REPL. You can just use luau-compile
instead.
* When an exception is thrown during parallel typechecking (usually an
ICE), we now gracefully stop typechecking and drain active workers
before rethrowing the exception.

New solver

* Include more source location information when we hit an internal
compiler error
* Improve the logic that simplifies intersections of tables

JIT

* Save testable type annotations to bytecode
* Improve block placement for linearized blocks
* Add support for lea reg, [rip+offset] for labels
* Unify X64 and A64 codegen for RETURN
* Outline interrupt handlers for X64
* Remove global rArgN in favor of build.abi
* Change A64 INTERRUPT lowering to match X64

* Fix autocompletion of if-then-else expressions
* Fix a potential crash surrounding improper use of `%*` in a string
format specifier
* All Python scripts now invoke Python via `python3` rather than
`python`.
* Improved error handling for string interpolation with too many
arguments.

- Fix DeprecatedGlobal warning text in cases when the global is deprecated without a suggested alternative
- Fix an off-by-one error in type error text for incorrect use of string.format
- Reduce stack consumption further during parsing, hopefully eliminating stack overflows during parsing/compilation for good
- Mark interpolated string support as experimental (requires --fflags=LuauInterpolatedStringBaseSupport to enable)
- Simplify garbage collection treatment of upvalues, reducing cache misses during sweeping stage and reducing the cost of upvalue assignment (SETUPVAL); supersedes #643
- Simplify garbage collection treatment of sleeping threads
- Simplify sweeping of alive threads, reducing cache misses during sweeping stage
- Simplify management of string buffers, removing redundant linked list operations

Also adjust benchmark runs to use config=profile and run clang for all benchmarks + gcc for runtime

bench: Implement first class support for callgrind (#570)
Since callgrind allows to control stats collection from the guest, this
allows us to reset the collection right before the benchmark starts.

This change exposes this to the benchmark runner and integrates
callgrind data parsing into bench.py, so that we can run bench.py with
--callgrind argument and, as long as the runner was built with callgrind
support, we get instruction counts from the run.

We convert instruction counts to seconds using 10G instructions/second
rate; there's no correct way to do this without simulating the full CPU
pipeline but it results in time units on a similar scale to real runs.

Sync to upstream/release/505 (#216)
- Improve error recovery during type checking
- Initial (not fully complete) implementation for singleton types (RFC RFC: Singleton types #37)
- Implement a C-friendly interface for compiler (luacode.h)
- Remove C++ features from lua.h (removed default arguments from luau_load and lua_pushcfunction)
- Fix lua_breakpoint behavior when enabled=false
- Implement coroutine.close (RFC RFC: coroutine.close #88)

Note, this introduces small breaking changes in lua.h:

- luau_load env argument is now required, pass an extra 0
- lua_pushcfunction now must be called with 3 arguments; if you were calling it with 2 arguments, pass an extra NULL; if you were calling it with 4, use lua_pushcclosure.

These changes are necessary to make sure lua.h can be used from pure C - the future release will make it possible by adding an option to luaconf.h to change function name mangling to be C-compatible. We don't anticipate breaking the FFI interface in the future, but this change was necessary to restore C compatibility.

Closes #121
Fixes #213
