Patch 

This patch has been tested on powerpc64-linux-gnu with no regressions and also
test for spu-elf with no regressions.  I have not looked into the code size
differences though but it should just decrease them instead of increase them as
we change a load to a move which then maybe register rename can rename
registers around to get one less register usage.
