rs6000: Implement cstore for signed Pmode register compares

This implements cstore for the last case we do not yet handle, using
the superopt algo from the venerable CWG.  The only integer cases we
do still not handle after this are for -m32 -mpowerpc64.

* (cstore<mode>4_signed): New expander.
(cstore<mode>4): Call it.
