[PATCH] [analyzer] Make realloc(ptr, 0) handling equivalent to malloc(0).

[Joerg Sonnenberger]

I don't believe we have to change anything here. The historic behavior of realloc(ptr, 0) is free(ptr) + returning NULL. That is also valid behavior under C11 where the behavior of malloc(0) is implemtation defined.
