[PATCH] [ARM]: Extend -mfpu options for half-precision and vfpv3xd

[Javed Absar]

Hi Renato:
Regarding your comment on VFPV3XD, I have added tests to in my patch (http://reviews.llvm.org/differential/diff/28232/) and tests for all other cases as well. These options are supported by gcc and vfpv3xd- is a valid option for r5.
