[IRPrinting] Improve module pass printer to work better with -filter-print-funcs Summary: Previously module pass printer pass prints the banner even when the module doesn't include any function provided with `-filter-print-funcs` option. This introduced a lot of noise, especailly with ThinLTO. This diff addresses the issue and makes the banner printed only when the module includes functions in `-filter-print-funcs` list.

; Check pass name is only printed once.
IR printing for single function with the new pass manager. Summary: The IR printing always prints out all functions in a module with the new pass manager, even with -filter-print-funcs specified. This is being fixed in this change. However, there are two exceptions, i.e, with user-specified wildcast switch -filter-print-funcs=* or -print-module-scope, under which IR of all functions should be printed.

[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
