Revision r280064 adds new options -fdenormal-fp-math and passes through option -ffast-math to CC1, but it included a wrong llvm regression tests which was removed in r280065.  Although regression test noexceptionsfpmath.c makes sure -fno-trapping-math ends up as a function attribute, this adds a test that explicitly checks the driver output for -fno-trapping-math.
