  Reland "[llvm-exegesis] Add support for pinning benchmarking process to a CPU (#85168)"

This reverts commit 5e3d48a68096a0017a0fa4bb89f2d48767c8a7e4.

This relands commit 9886788a8a500a1b429a6db64397c849b112251c.

This was originally causing build failures on more esoteric platforms
that have different definitions of getcpu. This is only intended to be
supported on x86-64 currently, so just use preprocessor definitions to
special case the function.
