Calling a static method on a type with no static method gives undeclared module error

This is pretty confusing, it'd be nice to at least mention that there isn't a static method with that name like in the second run where there is another static method.

I presume this is because static methods create a secret mod with the same name as the type, one possible resolution would be to always create this mod rather than only doing so when required.

New example:

struct Foo;
fn main() {
    Foo::bar();
}

(The ERROR lines should disappear after #14239 lands.)
