dereference()

static llvm::Optional< DereferenceInfo > dereference ( ProgramStateRef  State, const FieldRegion *  FR  )

static

Dereferences FR and returns with the pointee's region, and whether it needs to be casted back to it's location type.

If for whatever reason dereferencing fails, returns with None.
