Debugger not always showing pointer types as such

Currently, Qt Creator does not always show pointer types as such in the debugger.
Steps to reproduce:

1) Set up a new project with the sample program given at the end that uses `QString` pointer types.
2) set up the project to use either GDB or LLDB as debugger
3) set a breakpoint for the `return a.exec()`
4) start program in debugger
5) check what the debugger view shows for the local variables, in particular `str`, `ptr` and `ptrptr`

Result:

The following values are shown in the "Name", "Value" and "Type" columns:

• str, "hello", QString
• ptr, "hello", QString
• ptrptr, "hello", QString

Expected result:

Since `ptr` and `ptrptr` are of pointer types `QString*` and `QString**`, those should be shown in their "Type" column, i.e.:

• str, "hello", QString
• ptr, "hello", QString *
• ptrptr, "hello", QString * *

Small sample program:

    #include <QCoreApplication>

    int main(int argc, char *argv[])
    {
        QCoreApplication a(argc, argv);
        QString str("hello");
        QString *ptr = &str;
        QString **ptrptr = &ptr;
        return a.exec();
    }

I also tested this with the current development version (master branch as of commit 0f96f735f009a8f79a97ef81183bb43eaedc3a1e).
