A more precise description would be something along the lines
When in 32-bit arch a 64-bit key value doesn't fit into a pointer,
so hash_table_u64 internally use a pointer to a struct containing
the 64-bit key value.
Fix _mesa_hash_table_u64_clear() to handle the 32-bit case by
creating a temporary hash_key_u64 to pass to the hash function.
