[PATCH] D88806: [SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown

[Roman Lebedev via Phabricator via llvm-commits]

Okay. While i could continue pushing through with fixes to this approach,
by now it is quite clear that those aren't fixes, but ad-hoc hacks
that just hide the fact that casts are implicit,
which is normally fine, but not here.

So i'll take a step back here, and re-approach this with @efriedma's
original idea from https://bugs.llvm.org/show_bug.cgi?id=46786#c20.

Thanks.
