Yeah, that would totally work for me as well.

(I find that there's a small difference in style between llvm and clang tests in general, where llvm tests usually run with fixed target triples to test exactly the intended case, while many clang tests run for the build default target and have ifdefs for platform differences. But either is fine with me.)
