[PATCH] D89847: [SCEV] Drop cached ranges of AddRecs after flag update

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev updated this revision to Diff 303751.
mkazantsev added a comment.

Added elaborate comment, added assert that we don't pessimize the flags.

For some reason, it's no longer helpimg srem.ll. There has been a lot of related patches merged, one of them broke it?
