spu.md ("mov<mode>"): Use nonimmediate_operand predicate for destination operand.
* config/spu/spu.md ("mov<mode>"): Use nonimmediate_operand
predicate for destination operand.
* config/spu/spu.c (spu_expand_mov): If move destination is an
invalid subreg, perform move in the subreg's inner mode instead.
