Billy Robert O'Neal III e52a34bd9d Allow a standard library to implement conditional noexcept for optional and unique_ptr hash functions.
These tests were unconditionally asserting that optional and unique_ptr declare throwing hashes, but MSVC++ implements conditional noexcept forwarding that of the underlying hash function. As a result we were failing these tests but there's nothing forbidding strengthening noexcept in that way.

Changed the ASSERT_NOT_NOEXCEPT asserts to use types which themselves have non-noexcept hash functions.

Marshall Clow 7c803385a7 Implement P0599: 'noexcept for hash functions'. Fix a couple of hash functions (optional<T> and unique_ptr<T>) which were mistakenly marked as 'noexcept'. Reviewed as https://reviews.llvm.org/D31234

Eric Fiselier f9127593a9 Implement P0513R0 - "Poisoning the Hash"
Summary:
Exactly what the title says.

This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it.

See http://wg21.link/P0513R0 for more info.

If there are no comments in the next couple of days I'll commit this
