[PATCH v2, rs6000] Use $ instead of . for PC

[Bill Schmidt]

Hi,

Here's the same patch with corrected test cases.  This has now passed
bootstrap and testing on powerpc64-linux-gnu and powerpc64le-linux-gnu
with no regressions.  Is this okay for trunk?

Hopefully tomorrow early I will have a separate patch also changing
"setcr eq" to "setcr 2" to accommodate the AIX assembler.

Thanks,
Bill
