[Bug libstdc++/42242] vector::resize unnecessarily calls null constructor

[redi at gcc dot gnu dot org]

On second thoughts, it might be necessary to split it into two overloads for
C++1x, because this should work:

#include <vector>

struct moveable {
    explicit moveable(int) { }
    moveable(const moveable&) = delete;
    moveable(moveable&&) { }
};

int main()
{
    std::vector<moveable> v;
    moveable m(0);
    v.resize(1, m);
}
