I wonder if we can add a code-size test harness.  Using GNU size
for examle, if available and a new dg-final { object-size SIZE } that
fails when the size is greater than the specified one (of course all
object-size tests with specific target restrictions).

I would have started on this myself, but my TCL-fu causes me to jump
off such tasks very quickly ;)

Richard.
