[clang-tidy] readability-implicit-bool-conversion.AllowPointerConditions doesn't work on more complex expressions

[equeim]

struct Obj {
    int data;
}

void foo(Obj* obj) {
    // OK
    if (obj) {
        if (obj->data == 42) {
        }
    }

    // Warning
    if (obj && obj->data == 42) {
    }
}

If pointer is dereferenced in the same conditional expression after null pointer check then clang-tidy warns even if readability-implicit-bool-conversion.AllowPointerConditions is set to true. I believe that this option should allow this too.

```c++ struct Obj { int data; }

void foo(Obj* obj) {
// OK
if (obj) {
if (obj->data == 42) {
}
}

// Warning
if (obj && obj->data == 42) {
}

}

If pointer is dereferenced in the same conditional expression after null pointer check then clang-tidy warns even if `readability-implicit-bool-conversion.AllowPointerConditions` is set to true. I believe that this option should allow this too.
