[PATCH] D40347: [JumpThreading] Restrict PRE across instructions that don't pass control to successors

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

This looks simple enough and similar to how we handle other optimizations in presence of guards (there were previous issues with JT around guards that were fixed with isGuaranteedToTransferExecutionToSuccessor as well).

Pls wait and see for a day or two if anyone has other comments.
