This adds some SPARC feature flags to clang, for those that we have in common with GCC:

- `-m[no-]fpu`
- `-m[no-]fsmuld`
- `-m[no-]popc`
- `-m[no-]vis`
- `-m[no-]vis2`
- `-m[no-]vis3`
- `-m[hard/soft]-quad-float`

All have the same meanings as GCC's options (https://gcc.gnu.org/onlinedocs/gcc/SPARC-Options.html).

This fixes, among other things, the -mno-fpu part of bug #40792 (https://github.com/llvm/llvm-project/issues/40792).
