Checking FP function attribute values and adding more build attribute tests.

This renames the function for checking FP function attribute values and also
adds more build attribute tests (which are in separate files because build
attributes are set per file).

+; Check FP options -fno-trapping-math and -fdenormal-fp-math. They are passed
