Broken rendering under Asahi Linux (M1 GPU) when compiling with gcc #67

Rendering is broken under Asahi; it seems like certain 2D elements work, but anything 3D fails to render.

The console output only mentions some stalled compiles; let me know if there's anything in particular I can do to help debug!

Screenshot_20241117_172157 With PARALLEL_RDP_SMALL_TYPES=0 we get some other interesting broken output.

Have narrowed this down to gcc; it is not actually a driver issue. Clang is fine; gcc without optimizations is fine. UB sanitizer does not reveal anything illuminating. Still investigating.
