Is there any real purpose to implementing `Copy` versus just implementing
`operator :=` (or `operator Implicit` when in {$mode Delphi})? Those can be
inlined, and in practice are used in essentially all the places `Copy` is.
By which I mean, IIRC you never really see calls to `fpc_copy_proc` in the
generated assembler unless you've specifically implemented `Copy` yourself.
