Build failures on GCC 8 #51

GCC 8 has some limitations with regards to conditional noexcept, it seems. For example, trying to use push_back results in:

error: cannot call member function ‘constexpr void std::experimental::fcv_detail::storage::trivial<T, Capacity>::emplace_back(Args&& ...) [<snip>]’ without object
                 noexcept(emplace_back(forward<U>(value))))
                          ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~

This can be worked around by using noexcept(declval<fixed_capacity_vector>().emplace_back(forward<U>(value)))).

I did this in my local copy: lethal-guitar/RigelEngine@2eae5a6

I'd be happy to make a PR if desired.
