Make the wmma intrinsic type signatures to be canonical. We need a type signature as long as the type is not fixed. However, when an argument's type matches a previous argument's type, we do not need the signature for this argument. This patch fixes three general cases: 1. add missing signatures 2. remove signatures for matching arguments 3. reorer the signatures -- return type signature should always appear first
