Improve pointer hash function to include all bits
The hashtab pointer hash function is not very good. It throws most of the
bits in the pointer away.
This changes pointer_hash to use the mix code from jhash function that mixes
all the bits on the pointer and makes them dependent on each other, before doing
the modulo.
