History

Reapply "[VPlan] Fold NOT into predicate of wide compares." (#130347 )

This reverts commit 8dd160f4767f971572eac065c8650d9202ff5bf9.

The recommit contains an adjustment to planContainsAdditionalSimplifications,
which considers changes to the original predicate for compares.

Original commit message:

Add simplification to fold negation into a compare, if the negation is
the only user of the compare. This removes a number of redundant
negations.
