After removal of Darwin as a PowerPC subtarget, the VRSAVE save/restore/spill/update code is dead, so remove it while keeping support for vrsave and related instruction aliases for inline asm. I've pre-commited tests to document the existing vrsave handling in relation to @llvm.eh.unwind.init <https://reviews.llvm.org/rG45f008704df2680660ee82a7c3543d3ac9499a99> and inline asm usage <https://reviews.llvm.org/rG175f6e309ab911d43ab21707587615341112f3b5> to show this patch doesn't change the exiting behavior.
