Don't change the AArch64 intrinsics and move the test to Sema.

Apply review comments from Renato:
- simplify condition for enabling __ARM_FEATURE_FMA
- use cortex-a7 instead of cortex-a8 for testing since this is a real use case.

I've updated the patch to fix the defaults when the cpu is not specified.
Renato, Tim, could you have a look at this again please?
