Can you rewrite the test so you don't need to include math.h?  You don't need the whole header; you just need `extern "C" float expf(float);`.

We try to avoid including system headers in clang regression tests so the tests work consistently across platforms.  If we actually need to run something natively for some reason, we it in llvm-test-suite.
