This changes --print-before/after to be a list of strings rather than legacy passes. (this also has the effect of not showing the entire list of passes in --help-hidden after --print-before/after, which IMO is great for making it less verbose). Currently PrintIRInstrumentation passes the class name rather than pass name to llvm::shouldPrintBeforePass(), meaning llvm::shouldPrintBeforePass() never functions as intended in the NPM. There is no easy way of converting class names to pass names outside of within an instance of PassBuilder. This adds a map of pass class names to their short names in PassRegistry.def within PassInstrumentationCallbacks. It is populated inside the constructor of PassBuilder, which takes a PassInstrumentationCallbacks. Add a pointer to PassInstrumentationCallbacks inside PrintIRInstrumentation and use the newly created map. This is a bit hacky, but I can't think of a better way since the short id to class name only exists within PassRegistry.def. This also doesn't handle passes not in PassRegistry.def but rather added via PassBuilder::registerPipelineParsingCallback(). llvm/test/CodeGen/Generic/print-after.ll doesn't seem very useful now with this change.
