[llvm] [ADT] Update hash function of uint64_t for DenseMap (PR #95734)

This looks conceptually fine, but I think you need to do the same thing for the `unsigned long` type for the case where it is 64-bits large. On 64-bit Linux targets uint64_t will typically be a typedef for unsigned long, not unsigned long long.
