rs6000: enable SImode in FP register on P7
gcc/
PR target/88558
* config/rs6000/rs6000.cc (rs6000_hard_regno_mode_ok_uncached):
Enable SImode on FP registers for P7.
* config/rs6000/rs6000.md (*movsi_internal1): Add fmr for SImode
move between FP registers. Set attribute isa of stfiwx to "*"
and attribute of stxsiwx to "p7".
