[PATCH] D87000: Add a new hidden option -print-changes that reports in a patch-like notation when a pass actually changes the IR.

[Jamie Schmeiser via Phabricator via llvm-commits]

Note that this code makes use of the linux diff function to determine what has changed in the IR.  This will likely require altering for other platforms, which is a future enhancement.  The testing may require attention before this PR can land and any suggestions on how to handle this would be appreciated.
