[Support][X86] Change getHostNumPhsicalCores() to return number of physical cores enabled by affinity
Fixes https://bugs.llvm.org/show_bug.cgi?id=45556
While here, make the x86-64 code available for x86-32.
The output has been available and stable since
https://git.kernel.org/linus/3dd9d514846cdca1dcef2e4fce666d85e199e844 (2005)
```
processor:
...
physical id:
siblings:
core id:
```
Don't check HAVE_SCHED_GETAFFINITY/HAVE_CPU_COUNT. The interface is
simply available in every libc which can build LLVM.
