Fixup funcAttributes.

[ghost]

Fixup for #3501 which was missing support for typeof(func) or typeof(&property).

I will add this support to the documentation as well.

Note that there is one commented-out test. For some reason the @system attribute goes missing when using typeof(func) with the trait:

struct S
{
    void testSystem() @system { }
}

void main()
{
    // tuple("@system")
    pragma(msg, typeof(S.testSystem));

    // tuple("@system")
    pragma(msg, __traits(getFunctionAttributes, S.testSystem));

    // tuple()
    pragma(msg, __traits(getFunctionAttributes, typeof(S.testSystem)));
}

Can you please file a bug report for the missing @system?
