That is a contradiction in terms. If it's user-defined, then it could
do anything. If it's trivial, then it does trivial things. A trivial
default constructor is a no-op. A trivial copy/move constructor does a
bitwise copy.

What could go into a user-defined constructor that's trivial besides
*nothing*? If your user-defined trivial constructor takes parameters,
what could a trivial constructor do with those parameters besides
nothing?
