[NewPM] Cleanup IR printing instrumentation

[aeubanks]

Summary

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.

test fixes

Thanks for doing this. There are a couple of comments/asserts that were missed...The only real thing is that the functionality of unwrapping Any is repeated many times... perhaps a function taking lambdas for what to do with each type of IR would be useful, probably in the header with Any? WDYT?

llvm/lib/Passes/StandardInstrumentations.cpp

195–196

Remove second sentence of this comment. It is no longer valid.

217–218

"made a pair" => "a Module"

222

This could be changed to an assert and then the llvm_unreachable can be removed.

280

Again, assert this and remove llvm_unreachable.

323

Asert and remove llvm_unreachable.

362

Assert and remove the llvm_unreachable. The basic form of this function appears 4 or 5 times...would it make sense to have a function taking lambdas for the varying actions (in this case, calling printIR) to common up the unpacking logic associated with Any?

[aeubanks]

address comments

[aeubanks]

I'm not sure that having a helper method with 4 lambdas is any cleaner. Normal control flow in a function is easier to read and understand, and not really that much more code.

llvm/lib/Passes/StandardInstrumentations.cpp

222

I kinda prefer the symmetry.

 ; change over time, the checks for disabling passes are written in a
