[PATCH] D110290: [JumpThreading] Ignore free instructions

[Hans Wennborg via Phabricator via llvm-commits]

hans added a comment.

This caused compiler crash when building Chromium. See https://bugs.chromium.org/p/chromium/issues/detail?id=1252762#c8 for a reproducer, and the top of that bug for the stack dump.

I've reverted in 4604695d7c20e72b551a1a5224f3de877cb41bd3 <https://reviews.llvm.org/rG4604695d7c20e72b551a1a5224f3de877cb41bd3> in the meantime.
