Doing this when computing a canonical signature didn't really make sense because canonical signatures are not canonicalized any more strongly _with respect to the builder_; they just canonicalize their requirement types. Instead, let's do these checks after creating the signature in computeGenericSignature(). The old behavior had another undesirable property; since the canonicalization was done by registerGenericSignatureBuilder(), we would always build a new GSB from scratch for every signature we compute. The new location also means we do these checks for protocol requirement signatures as well. This flags an existing fixed crasher where we still emit bogus same-type requirements in the requirement signature, so I moved this test back into an unfixed state.
