typeof incorrectly removes qualifiers in some situations (with C clang/gcc modes)

Environment

• OS and Version: Windows 10
• VS Code Version: 1.100.2
• C/C++ Extension Version: 1.25.3

Bug Summary and Steps to Reproduce

Bug Summary:

Steps to reproduce:
Use typeof with a qualified or atomic lvalue obtained from dereferencing a pointer to a qualified or atomic type, for example:

typedef typeof(*(const int*)0)x;

When hovering over this definition, it reports x as being the type int.

Expected behavior:
The reported type of x should be const int.

Additional context

This issue does not occur when using an lvalue derived from a name instead of dereferencing a pointer, e.g.:

Primero reproduce el resultado del hover con el ejemplo de C23 typeof proporcionado en la configuración de Windows GCC indicada y, después, sigue la información de tipo de IntelliSense para un puntero desreferenciado a un tipo cualificado o atómico. Se considera terminado cuando el tipo indicado conserva el cualificador const o atomic, también para la reproducción proporcionada.
