[PATCH] D86360: Add new hidden option -print-changed which only reports changes to IR

[Jamie Schmeiser via Phabricator via llvm-commits]

@MaskRay,   https://reviews.llvm.org/D87000 moves a bunch of the code into a separate file, rather than deleting it.  -print-changed, by itself, doesn't add enough to justify it's own file but once you add in -print-changes and -dot-cfg-changes, it grows to a significant amount of code, so I moved it to a separate file.  I had already marked the other PRs as children in a chain, which can be seen in the stack tab of the revision contents.  Is there another way that I should indicate the relationship between the PRs?  Thanks for your comments about these 3 PRs.  I have found these ways of looking at the changes very useful, particularly -dot-cfg-changes.  (Shameless promotion alert:)  I will be presenting these three ways of looking at the IR in my tutorial at the upcoming virtual developers meeting, including a demo of -dot-cfg-changes.
