clang -cc1 accepts -Ofast. I did not add it to flang -fc1 because this seems redundant because the compiler driver will always resolve -Ofast into -O3 -ffast-math (I added a test for this). -menable-infs is removed from the frontend-forwarding test because if all of the fast-math component flags are present, these will be resolved into the fast-math flag. Instead -menable-infs is tested in the fast-math test. Specifying -ffast-math to the compiler driver causes linker invocations to include crtfastmath.o.
