  [StructuralHash] Support Differences

This comutes a structural hash while allowing for selective ignoring of
certain operands based on a custom function that is provided.
Instead of a single hash value, it now returns FunctionHashInfo which
includes a hash value, an instruction mapping, and a map to track the
operand location and its corresponding hash value that is ignored.
