fix 303127  Power test suite fixes for frsqrte, vrefp, and vrsqrtefp instructions

The frsqrte and vrefp instructions produce an approximate result.
According to the ISA document for the POWER processor, the result will
vary in its precision for different processor implementations.  This patch
fixes the masks to be applied to the results to remove the variability
in the results.  The expected output files are also updated to reflect the
change in the result given the new masking of the result.
