("[PATCH for-8.0 v3 00/34] tcg misc patches")

This contains two patches that exercise the register pair patches
within the "tcg misc patches" patch set.  Then a couple of misc
cleanups, then support for the MIE2, MIE3, and POPCOUNT features.

One thing to play with: the middle-end can expand ctz based on
either clz or ctpop, and for z16 we now have both.  I've got an
idea that for s390x the most general case of the expansion would
be better with clz.  Which leads me to wonder if there's a better
way to manage such expansions, but I haven't thought about it
too much yet.
