Detailed Description

A reference operation in the hashtable is representation as
the vuse, representing the memory state at the time of
the operation, and a collection of operands that make up the
addressing calculation.  If two vn_reference_t's have the same set
of operands, they access the same memory location. We also store
the resulting value number, and the hashcode.
