Summary: This *might* be the last fold for `sink-addsub-of-const.ll`, but i'm not sure yet. As far as i can tell, there are no regressions here (ignoring x86-32), all changes are either good or neutral. This, almost surprisingly to me, fixes the motivational tests (in `shift-amount-mod.ll`) `@reg32_lshr_by_sub_from_negated` from [[ https://bugs.llvm.org/show_bug.cgi?id=41952 | PR41952 ]]. https://rise4fun.com/Alive/vMd3 Reviewers: RKSimon, t.p.northover, craig.topper, spatel, efriedma Reviewed By: RKSimon Subscribers: sdardis, javed.absar, arichardson, kristof.beyls, jrtc27, atanasyan, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D62774 llvm-svn: 362488
