Subject: [v3] More work on std::tuple (and pair)

Hi,

this improves the constraining in std::tuple (and in principle should render redundant the 1-element spec modulo c++/49225) and also tweak std::pair to use __and_ in order to minimize the number of instantiations. Plus smaller changes.

Tested x86_64-linux, committed to mainline.

Paolo.
