Fix accidental ADL in std::allocator_traits meta-programming.

There were a number of cases where __double_underscore functions,
for example __has_construct_test, were called without being qualified,
causing ADL to occur. This patch qualifies those calls to avoid this
problem.

Thanks to David L. Jones for point out the issue initially.
