[PATCH] D75799: [JumpThreading] Don't create PHI nodes with "is.constant" values

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

It still seems to be a perfectly reasonable optimisation under  the semantics of `is.constant`. The code here seems to be an abuse of it though and makes assumptions that are not sensible.
