The AllConstant check needs to be moved out of the if/else if chain to
avoid a test regression. The "there is no SimplifyZExt" comment puzzles me,
since there is SimplifyCastInst. Additionally, the Simplify* calls
seem to not see the operand as constant, so this needs to be tried if
the simplify failed.
