I have reverted that syntax change. We had initially rolled it out internally,
and later found that our assembler didn't like that syntax change, so we rolled
it back. I forgot to roll it back on the upstream branch.
To our understanding, the .save directive is for unwinding, and only accepts
GPR's. .vsave isn't the correct directive to use either, since those only
accept DPR's. In the end, we decided to just have those .save's refer to the
actual GPR's.
