POWERPC: Fix handling of stfiwx math emulation

patch ba02946a903015840ef672ccc9dc8620a7e83de6 in mainline

Its legal for the stfiwx instruction to have RA = 0 as part of its
effective address calculation.  This is illegal for all other XE
form instructions.

Add code to compute the proper effective address for stfiwx if
RA = 0 rather than treating it as illegal.
