Chandler Carruth b698d5964d [PM] Fix a really nasty bug introduced when adding PGO support to the 
new PM's inliner.

The bug happens when we refine an SCC after having computed a proxy for
the FunctionAnalysisManager, and then proceed to compute fresh analyses
for functions in the *new* SCC using the manager provided by the old
SCC's proxy. *And* when we manage to mutate a function in this new SCC
in a way that invalidates those analyses. This can be... challenging to
reproduce.

I've managed to contrive a set of functions that trigger this and added
a test case, but it is a bit brittle. I've directly checked that the
passes run in the expected ways to help avoid the test just becoming
silently irrelevant.

This gets the new PM back to passing the LLVM test suite after the PGO
improvements landed.
