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.
