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.
