rs6000: Fix PR67346
"*ior<mode>_mask" is a define_insn_and_split, so it shouldn't use
can_create_pseudo in its instruction condition, because IRA can then
create such an instruction, and the condition becomes false before
the insn is split. Use a scratch instead.

* config/rs6000/rs6000.md (*ior<mode>_mask): Use a match_scratch.
