Proposed patch to fix the problem
I haven't yet done a full bootstrap build/make check, but I believe this patch
fixes the problem.
The problem was for non-VSX systems, it still allowed 0.0 as the second
argument for the DF->TF expand insn, and reload tried to use it. I rewrote it
to only require register for pre-VSX systems.
