[llvm] [SampleFDO] Stale profile call-graph matching (PR #95135)

[David Li via llvm-commits]

https://github.com/david-xl commented:

Does the algorithm need to be iterative? For instance, at top level we have profile function 'foo' calling profile function bar, and IR function 'foo_new' calling IR function 'bar_new'. Can the algorithm recursively match bar with bar_new? If yes, perhaps add a test case.
