Benjamin Kramer c79888d90d MergeFunc: Make pointer and integer types generate the same hash.
The logic that actually compares the types considers pointers and integers the
same if they are of the same size. This created a strange mismatch between hash
and reality and made the test case for this fail on some platforms (yay,
test cases).
