Changed APValue to differentiate with null pointer and pointers casted from integer. Fixed casting integer to pointer.

Refactored isNullPtrZero to use just QualType as parameter.

Added tests for casting integer to pointer, initialization of static and function-scope variable, and cast pointer to bool.
