Subject: [v3] Use move_if_noexcept in std::vector

Hi,

the below starts using it, for correctness wrt move constructors which can throw. For sure we are missing the optimization which uses the default-constructor + swap when the type isn't nothrow move constructible, per Note 5 in n3050, for example.

Tested x86_64-linux, committed.

Paolo.
