rL240929: [ARM]: Extend -mfpu options for half-precision and vfpv3xd
Summary

Some of the the permissible ARM -mfpu (floating-point hardware) options, which are already supported in GCC, are currently not present in llvm/clang. This patch adds, namely, the options 'neon-fp16', 'vfpv3-fp16', 'vfpv3-d16-fp16', 'vfpv3xd' and 'vfpv3xd-fp16. These options are related to half-precision floating-point and single precision.
