[PATCH] [analyzer][Review request] Improved checker lists.

[Антон Ярцев]

Not sure that I've got the idea. Each example is designed for the particular case of a dangerous pointer usage. In order:
The first example illustrates the usage of a pointer as an operand of a //delete//-expression - OK.
The second example is a modified example from the C++ spec - a call to a virtual function of an object whose lifetime has ended. Did you mean to call a destructor or keep a pointer to a field within the object instead? Isn't a call to a virtual function a usage of an old object?
The last three examples illustrate the following cases:
- the pointer is implicitly converted to a pointer to a base class type
- the pointer is used as the operand of a static_cast (except when the conversion is to void*, or to void* and subsequently to char*, or unsigned char*)
- the pointer is used as the operand of a dynamic_cast
Do you think the corresponding tests should be modified somehow?
