[PATCH] D86657: Add new hidden option -print-crash-IR that prints out IR that caused opt pipeline to crash

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

Is this ready to land?

Also, on further thought, do we really need all the mutex code? This is supposed to be for debugging anyway, not really used in production code like JITs.
