Roman Lebedev 7ee6c40247 Revert "Reland "[SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown"" and it's follow-ups ... While we haven't encountered an earth-shattering problem with this yet, by now it is pretty evident that trying to model the ptr->int cast implicitly leads to having to update every single place that assumed no such cast could be needed. That is of course the wrong approach. Let's back this out, and re-attempt with some another approach, possibly one originally suggested by Eli Friedman in https://bugs.llvm.org/show_bug.cgi?id=46786#c20 which should hopefully spare us this pain and more. This reverts commits 1fb6104293, 7324616660, aaafe350bb, e92a8e0c74. I've kept&improved the tests though.		2020-10-14 16:09:18 +03:00
