rs6000: Make 32 bit stack_protect support prefixed insn [PR111367]
As PR111367 shows, with prefixed insn supported, some of
checkings consider it's able to leverage prefixed insn
for stack protect related load/store, but since we don't
actually change the emitted assembly for 32 bit, it can
cause the assembler error as exposed.
Mike's commit r10-4547-gce6a6c007e5a98 has already handled
the 64 bit case (DImode), this patch is to treat the 32
bit case (SImode) by making use of mode iterator P and
ptrload attribute iterator, also fixes the constraints
to match the emitted operand formats.
