[PATCH] D92152: [SCEV] Use isKnownPredicateAt in isLoopBackedgeGuardedByCond

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

Maybe it's because `isKnownPredicateAt` makes an extra call to `isKnownPredicate` which we don't really need. Let's try more lightweight version with `isBasicBlockEntryGuardedByCond`. This should not introduce extra overhead.
