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

This is an update based on changes that have been made to the code in the review
for https://reviews.llvm.org/D86360.  I have moved much of the code and templates into
a new header and body files as it is becoming more complex.  I have also changed
some of the class names from being "change printer" based to "change reporter"
based because it doesn't imply how the changes are shown (ie, the changes do not
necessarily need to be printed).
