What's Changed

• CodeGen: Fix a typo in X64 (dis)assembler by @zeux in #1238
• Optimize table.concat. This function is now 1.4x-2x faster. #1243
• Optimize table.maxn. This function is now 5-14x faster
• Add benchmarks for native compilation with type info enabled by @vegorov-rbx in #1244
• Reserve Luau stack space for error message.

New Solver

• Globals can be type-stated, but only if they are already in scope
• Fix a stack overflow that could occur when normalizing certain kinds of recursive unions of intersections (of unions of intersections...)
• Fix an assertion failure that would trigger when the __iter metamethod has a bad signature

Native Codegen

• Type propagation and temporary register type hints
• Direct vector property access should only happen for names of right length
• BytecodeAnalysis will only predict that some of the vector value fields are numbers
