Needed one more tweak; when dealing with a capture proxy, always bail
out and never fall through to the warning-handling
code below the DR 2211 check.

It seems to me that there's a discrepancy in handling explicit
default constructors. Based on my tests, this works:
struct X {explicit X() {}};
void f(X) {}
int main()
{
f({});
}
However, if the explicit constructor is defaulted, gcc accepts the code:
struct X {explicit X() = default;};

Since N3994 ended up being rejected and was never included
in C++17, I want to remove the support for it. It's easy to bring
it back if such a facility is resurrected, but for now, let's remove
