Do not emit deprecated v8-style FP branches when targeting a v9 processor.
Also, change the v9 FP compare definitions on TableGen files so that it
allocates over the entire FP CCR set instead of being hardcoded to %fcc0,
to match the behavior of the branch instructions.
(Though at the moment LLVM doesn't seem to use anything other than %fcc0)
Fixes bug #17834 (https://github.com/llvm/llvm-project/issues/17834).
