building clang against llvm-libc fails with:
```
In file included from /llvm-project-main/llvm/lib/Support/Threading.cpp:67:
/llvm-project-main/llvm/lib/Support/Unix/Threading.inc:348:3: error: use of undeclared identifier 'CPU_ZERO'
348 | CPU_ZERO(&Enabled);
| ^
/llvm-project-main/llvm/lib/Support/Unix/Threading.inc:380:11: error: use of undeclared identifier 'CPU_ISSET'
380 | if (CPU_ISSET(CurProcessor, &Affinity))
| ^
/llvm-project-main/llvm/lib/Support/Unix/Threading.inc:381:9: error: use of undeclared identifier 'CPU_SET'
381 | CPU_SET(CurPhysicalId * CurSiblings + CurCoreId, &Enabled);
| ^
```
looks like these are macros we'd probably need to define in libc/include/llvm-libc-macros/linux/sched-macros.h.
