[NewPM][PassInstrumentation] IR printing support for (Thin)LTO Summary: IR printing has not been correctly supported with (Thin)LTO if the new pass manager is enabled. Previously we only get outputs from backend(codegen) passes, as they are still under legacy pass manager even when the new pass manager is enabled. This patch addresses the issue and enables IR printing for optimization passes with new pass manager + (Thin)LTO setting.

[NewPM][PassInstrumentation] Fix test added in r369024. llvm-lto2 doesn't treat "-" as stdout, so the test added in r369024 creates a file named "-.0". This patch makes the test look more like other tests that use llvm-lto2. llvm-svn: 369066

[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
