[PATCH] D63105: Add --print-supported-cpus flag for clang.

[Nick Desaulniers via Phabricator via llvm-commits]

nickdesaulniers added a comment.

@pirama and @kongyi pointed out to me that `-emit-llvm` tests don't require backend support, and that the undocumented (https://llvm.org/docs/CommandGuide/FileCheck.html) `REQUIRES:` tag would fix this.
