Ah, now I remember which features of the lazy LLDS code generator are not
supported in the new LLDS code generator:
	(1) --no-static-ground-terms
	(2) the `jump' and `fast' grades.

Do we really want to get rid of those?

Note that (1) is currently needed for structure reuse,
e.g. the tests in tests/general/structure_reuse.
