Move constructors are not noexcept

Eigen types now sport move constructors, but those move constructors are not noexcept in compilers that support it and care about it. This causes problems when containers use
std::move_if_noexcept and end up doing needless copies.
Please make the move constructors noexcept as appropriate.
