[PATCH] D12781: PGO IR-level instrumentation infrastructure

Also, can you begin to work on tests? I think right now the core algorithm is pretty good. There are some cleanups to the implementation that I'd like to see but I can do those post-commit if necessary. Right now the main missing piece needed before this is committed are tests.
