simplify_truncation changes the truncation of many operations into

Tested on powerpc64-linux. With this patch the rlwimi testcases work.
Is this okay for trunk?
The rlwimi tests? Are you referring to ppu-intrinsics or something else?

Ah, I don't see those in my tree yet. :-)
Any chance this would help 15596?
It doesn't help. To fix PR15596 we need to have bitfields handled
better before (and/or during) expand.
Noted. Thanks. Not that I think 15596 is all that important, but it
does taunt me every release -- it seems like we've got all stuff we need
in combine, but the APIs get in the way of optimizing it.
