This is a problem extracting the first subreg from a SCmode value.  Thia
occurs during reload after the point where pseudos can be created but we
need a pseudo to extract the subreg.  The problem is SCmode is the same
size as DImode on this target, so the subreg can't be extracted by a move.

I marked this a middle-end bug as the documentation indicates that complex
values are handled by it.
