Chad Rosier 45619cbc03 [driver] When using the -mfpmath= option, add an error message when trying to 
enable neonfp on a CPU that doesn't support NEON.

Chad Rosier 1f0e52e361 [driver] Create a new -mfpmath= option, which is used to control whether clang 
uses Neon instructions for single-precision FP.

-mfpmath=neon is analogous to passing llc -mattr=+neonfp.
-mfpmath=[vfp|vfp2|vfp3|vfp4] is analogous to passing llc -mattr=-neonfp.
