    vec.h: Uncomment static_assert
    
    Now that poly_int_pod has been removed and other changes mostly to use
    {quick,safe}_grow_cleared instead of {quick,safe}_grow for types with
    non-trivial default construction, we can enable even the last static
    assertion.  From now on, {quick,safe}_grow can only be used with
    trivially default constructible types.
