[NewPM] Don't error when there's an unrecognized pass name This currently blocks --print-before/after with a legacy PM pass, for example when we use the new PM for the optimization pipeline but the legacy PM for the codegen pipeline. Also in the future when the codegen pipeline works with the new PM there will be multiple places to specify passes, so even when everything is using the new PM, there will still be multiple places that can accept different pass names.

[NewPM] Support --print-before/after in NPM 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.
