Invert the TargetLowering flag that controls divide by consant expansion.
Add a new flag to TargetLowering indicating if the target has really cheap
signed division by powers of two, make ppc use it. This will probably go

Implement some more ISD::SDIV folds in the dag combiner
Remove now dead code in the x86 backend.
