SimplifyCFG doesn't look like a good place to put this as it is called multiple times and impacts compile time significantly.
Agreed with @jfb that having hasher as a separate pass which other passes can consume. @vish99 may have more ideas on hashing.
Hashing can be expensive and we could use clever tricks to make it cheaper. D52896 <https://reviews.llvm.org/D52896> could help, happy to provide more input.
