@s-barannikov I found the bug, its an embarassing one for me unfortunately, Im uploading a new patch to https://github.com/llvm/llvm-project/pull/83587 shortly. I will also be abandoning this PR as it is unnecessary for my change. 

I do think its a bit of an issue how many matchables aren't comparable right now even though they are functionally distinct and think there is an argument for something like this patch in the future, though as @kosarev points out, it should not be based off names.
