Clang Code Model doesn't follow signatures with arguments differing in constness

Declaring a function in a header such as:

void f(int x);

And defining it in a cpp file as:

void f(const int x) {}

Makes the clang code model lost. "Switching between declaration/definition" doesn't work. "Follow symbol under cursor" works from definition to declaration but not the other way around.

This problem does not impact the Qt Creator old code model.

This is valid C++ code and commonly used to tell the compiler that the copy of x will not be modified, without overwhelming the API user with implementation details. 

Thank you,
