Sync to upstream/release/568 (#865) * A small subset of control-flow refinements have been added to recognize type options that are unreachable after a conditional/unconditional code block. (Fixes https://github.com/Roblox/luau/issues/356). Some examples: ```lua local function f(x: string?) if not x then return end -- x is 'string' here end ``` Throwing calls like `error` or `assert(false)` instead of 'return' are also recognized. Existing complex refinements like type/typeof and tagged union checks are expected to work, among others. To enable this feature, `LuauTinyControlFlowAnalysis` exclusion has to be removed from `ExperimentalFlags.h`. If will become enabled unconditionally in the near future. * Linter has been integrated into the typechecker analysis so that type-aware lint warnings can work in any mode `Frontend::lint` methods were deprecated, `Frontend::check` has to be used instead with `runLintChecks` option set. Resulting lint warning are located inside `CheckResult`. * Fixed large performance drop and increased memory consumption when array is filled at an offset (Fixes https://github.com/Roblox/luau/issues/590) * Part of [Type error suppression RFC](https://github.com/Roblox/luau/blob/master/rfcs/type-error-suppression.md) was implemented making subtyping checks with `any` type transitive. --- In our work on the new type-solver: * `--!nocheck` mode no longer reports type errors * New solver will not be used for `--!nonstrict` modules until all issues with strict mode typechecking are fixed * Added control-flow aware type refinements mentioned earlier In native code generation: * `LOP_NAMECALL` has been translated to IR * `type` and `typeof` builtin fastcalls have been translated to IR/assembly * Additional steps were taken towards arm64 support
