Eric Fiselier 2d08bc9a9f Implement LWG 2148: Make non-enum default hash specialization well-formed ...

Summary:
This patch removes the static_assert for non-enum types in the primary hash template. Instead non-enum types create a hash<T> specialization that is not constructible nor callable.

negators

In C++03, a bunch of the arithmetic/logical/comparison functors (such as negate/bit_not.pass/logical_not) were defined as deriving from unary_funtion. That restriction was removed in C++11, but the tests still check for this. Change the test to look for the embedded types first_argument/second_argument/result_type. No change to the library, just more standards-compliant tests. Thanks to STL @ Microsoft for the suggestion.
