one.

To setne, not setune, which causes an assertion fault.

Nate, please verify that if InsertMask is 0, rlwimi shouldn't be used.
This fixes the crash and causes no PPC testsuite regressions.

If a two-address code whose first operand has uses below, it should be commuted
when possible.

allocation policies and much more.  All this complexity, and we have no
functionality change, woo! :)

When doing the initial pass of constant folding, if we get a constantexpr,
simplify the constant expr like we would do if the constant is folded in the
normal loop.

This fixes the missed-optimization regression in
Transforms/InstCombine/getelementptr.ll last night.
