Arseny Kapoulkine f2e6a8f4a5 Sync to upstream/release/507-pre (#286) ... This doesn't contain all changes for 507 yet but we might want to do the Luau 0.507 release a bit earlier to end the year sooner. Changes: - Type ascription (::) now permits casts between related types in both directions, allowing to refine or loosen the type (RFC #56) - Fix type definition for tonumber to return number? since the input string isn't guaranteed to contain a valid number - Fix type refinements for field access via [] - Many stability fixes for type checker - Provide extra information in error messages for type mismatches in more cases - Improve performance of type checking for large unions when union members are string literals - Add coverage reporting support to Repl (--coverage command line argument) and lua_getcoverage C API - Work around code signing issues during Makefile builds on macOS - Improve performance of truthiness checks in some cases, particularly on Apple M1, resulting in 10-25% perf gains on qsort benchmark depending on the CPU/compiler - Fix support for little-endian systems; IBM s390x here we go!		2021-12-10 14:05:05 -08:00
