QVarLengthArray: add support for emplacement
Take the rvalue insert() function and turn it into the emplace()
function. Reformulate rvalue-insert using emplace(). Lvalue insert()
is using a different code path, so leave that alone. This way, we
don't need to go overboard with testing.
[ChangeLog][QtCore][QVarLengthArray] Added emplace(), emplace_back().
