Actually I think this is already handled by PGOInstrumentation.cpp, in the sense that a function's entry count and branch weights are only populated if the counters are not pseudo (https://github.com/llvm/llvm-project/blob/831592d6171bc62f6991387546512b9cf2ce1c9e/llvm/lib/Transforms/Instrumentation/PGOInstrumentation.cpp#L2260-L2269). I'll drop this change and clean-up the unused synthetic count in a different change.

Sorry for the noise!
