With fix for the expensive checks build failure. Something about
expanding two rotates in type legalization caused a change in the
remapping tables that the expensive checks verifying wasn't expecting.
See comment in the code for how it was fixed.

Original commit message:
If the masking AND has multiple users we fail to remove it.
