Keep labels inside their inline assembly blocks and make byte-sized memory operands explicit where clang-cl requires their size.
Configure a Linux-hosted Ninja build with clang-cl, LLD, and the installed MSVC headers and libraries. Apply the compatibility settings required by bx.
Use aligned CRT allocation for bgfx render records so clang-cl-generated aligned SSE accesses cannot receive under-aligned storage.
Assemble the legacy MASM sources with native UASM instead of invoking ml.exe through Wine.
The build pipeline no longer invokes Wine after native UASM and LLVM RC replaced the remaining wrapper tools.

Summary
Add an experimental Linux-hosted Win32 cross-build using clang-cl with the MSVC
ABI, headers, and libraries. The branch also makes the C++ sources and legacy
assembly accepted by clang-cl, aligns bgfx render-record allocations, and adds a
VS Code IntelliSense example.
Behavior and compatibility
BX_CONFIG_DEBUGto match the bgfx libraries and allocates bgfx records alignment-correctly, keeping MSVC and clang-cl builds consistent.The codebase may still contain undefined behavior the supported MSVC build does not expose, so a successful clang-cl build is not runtime evidence.
Validate any clang-cl result separately.
Known clang-cl runtime observations:
Validation
built (Release, Ninja) with inherited warnings and no errors; LogStress passed, including 100,000 intact log lines.
Documentation
docs/BUILDING.mddocuments the experimental toolchain requirements,configuration, and the runtime limitation.
