[PATCH v3, rs6000] Use $ instead of . for PC, use "crset 2" instead of "crset eq"

Hi,
Here's another version of this patch incorporating the late-breaking news
that the AIX assembler doesn't comprehend the "eq" symbol. Same as
https://gcc.gnu.org/ml/gcc-patches/2018-01/msg01787.html but adding the
change to use "crset 2" instead.
This one is still regstrapping on BE/LE, trunk/7. If these all complete
successfully, is this okay for trunk and backport?
Thanks,
Bill
