[llvm] [MemProf] Add remarks for matched allocs and calls (PR #170379)

I'm hesitant to have both ORE and existing debug output which differ in behaviour. In this cases the ORE is not deduplicated (as you noted in the description). Can we make them equivalent so that later it would be trivial to remove the debug output?
