STL std::hash<T*> implementations have a tendency of just reinterpreting the pointer as a size_t. This is fast, but produces a bad hash, as most pointers tend to be 4 or 16 byte aligned. The lack of entropy in the LSBs causes clustering of hashmap slots. Use tint::utils::Hasher to get better hashes.
