mkazantsev added a comment.

The patch was reverted by https://reviews.llvm.org/rL312783 due to failures on internal tests. The failures are fixed
in this revision, specifically the previous version of the patch missed updates of `GreatestSeen`
and `Smallest` values in case of comparison against current IV value.

Failures fix, resubmitting for review.
