[Bug libstdc++/40296] [C++0x] std::exception_ptr comparisons

Curiously enough, N2857 doesn't even require that exception_ptr be usable in
conditions. I must have simply assumed that anything with _ptr in its name must
be a valid condition.

So yeah, if the ABI can take it, I'm all for removing that operator. Can it,
though?

If not, it's a pretty mess. We'd have to define a lot of comparison operators
to cover for the conversion, i.e. at least a quad (== and !=, with the
non-exception_ptr on the left and the right side) for int, long, and nullptr_t.
