PR7247: Extension to ignore global templates with same name as member

Downgrades the error to a warning in:

template<typename T> struct set{};
struct Value {
    template<typename T>
    void set(T value) {
    }
};
void foo() {
    Value v;
    v.set<double>(3.2);
}

I couldn't find a way to use this error in SFINAE, so I didn't keep it working
there. If anyone can send me a test case for that, I'll be happy to fix it.

Might be nice to include a motivating example?

You mean the traits one that's hard to work around? The simple motivating
example is above, and I can't find one that actually justifies the warning.
