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.
