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".
