[PATCH] D38182: test-suite: add cpu features detection in configuration

[Matthias Braun via Phabricator via llvm-commits]

This looks mostly fine.

- What about cross compilation scenarios? I think this should have a way to manually set the flags in that case.
- We need equivalent tests on the cmake side.
- This should only be committed when we have some tests that actually use it.

----------------
This should have X86 in the name, and probably shouldn't even do anything if the target triple isn't x86.
