I think that second point is going to need some evidence (at least in the form of transform stats I guess). D96881 <https://reviews.llvm.org/D96881> is another recent attempt to work around pointer types, and it looks like that one did regress others. This patch already shows regressions inside InstCombine itself, so that's not a great sign.
