For example, copying and moving a trivial type ends is the same.
However, currently we generate the code for both cases independently
instead of reusing the same underlying function.
This reduces the size of the Blender binary from `218.548.896` to
`218.355.552` bytes for me. So it's a reduction of about 200kb.
It's probably possible to reduce this even more, but that's for another day.
The main tricky thing here is telling the compiler that a `const` from a
function parameter can be cast away for trivial types (see code comment).
Maybe there is a better way to do this while making sure the compiler
doesn't generate unnecessary code.
