I found one problem with reg equivalences. They were just ignored. It is a
result of bad merging the big IRA patch and changes in IRA for last half year.
I found the problem solution improves the code size (at least for -O2). I'll
send the patch today.
But I guess it does not solve all the code size degradation. Therefore I
continue my work on the PR.
Thanks for the small tests, Richard. It saved a lot of my time.
