Any help with benchmarking this on targets other than x86_64

I ran CPU2000 and CPU2006 on PowerPC comparing the patch. CPU2000 had 3
benchmarks degrade in the 4%-6%range (254.gap, 168.wupwise,
173.applu).CPU2006 showed one benchmark, 410.bwaves, degrading 9%.I have
dug into applu/bwaves and saw nothing directly attributable to your
patch, degradations looked to be caused by idioms/oddities of the
PowerPC architecture related to minor scheduling differences and/or data
location.
