IR printing improvement for loop passes Summary: Loop-pass printing is somewhat deficient since it does not provide the context around the loop (e.g. preheader). This context information becomes pretty essential when analyzing transformations that move stuff out of the loop. Extending printLoop to cover preheader and exit blocks (if any).

; Besides of the loop itself it should be dumping loop pre-header and exits.

[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.

[NewPM] Cleanup IR printing instrumentation Being lazy with printing the banner seems hard to reason with, we should print it unconditionally first (it could also lead to duplicate banners if we have multiple functions in -filter-print-funcs). The printIR() functions were doing too many things. I separated out the call from PrintPassInstrumentation since we were essentially doing two completely separate things in printIR() from different callers. There were multiple ways to generate the name of some IR. That's all been moved to getIRName(). The printing of the IR name was also inconsistent, now it's always "IR Dump on $foo" where "$foo" is the name. For a function, it's the function name. For a loop, it's what's printed by Loop::print(), which is more detailed. For an SCC, it's the list of functions in parentheses. For a module it's "[module]", to differentiate between a possible SCC with a function called "module". To preserve D74814, we have to check if we're going to print anything at all first. This is unfortunate, but I would consider this a special case that shouldn't be handled in the core logic. Reviewed By: jamieschmeiser Differential Revision: https://reviews.llvm.org/D100231
