Sure, the hasher must skip all inputs that could differ in their literal
spelling, but I don't see why we have to hash them to a single global value. If
two semantically same Decls / Types are not literally the same, we skip the
input for both of them and the output hash will still be the same.
Do you have a concrete example in mind that you think should be tested?
