* hash.c (ll_hash): Hashing of pointers should take into
account alignment, otherwise only values divisible by the
alignment occur. This patch takes into considerations that
val values are pointers to object descriptors in a heap which
are four words wide, and so most likely aligned to 16 byte
boundaries (32 bit systems) or 32 byte boundaries (64 bit).
We need to shift.
