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.:

First reproduce the hover result with the provided C23 typeof example in the reported Windows GCC configuration, then trace the IntelliSense type information for a dereferenced pointer to a qualified or atomic type. Done means the reported type preserves the const or atomic qualifier, including for the supplied reproduction.
