ProgramState - This class encapsulates:
Together these represent the "abstract state" of a program.
ProgramState is intended to be used as a functional object; that is, once it is created and made "persistent" in a FoldingSet, its values will never change.

Initializes the region of memory represented by loc

Once initialized, all values loaded from any sub-regions of that region will be equal to V
, unless overwritten later by the program. This method should not be used on regions that are already initialized. If you need to indicate that memory contents have suddenly become unknown within a certain region of memory, consider invalidateRegions().
