    PR c++/87685 - generic lambda 'this' capture error.

    The standard says that in a generic lambda we should speculatively capture
    'this' if we see a call to an overload set that contains a non-static
member
    function, but it seems wrong to reject the program if we can't capture,
    since it might not actually be needed.
