Neither are bugs introduced by me.

The bugs were introduced by Jeff's patch to examine static initializers.
Since the simplification test is is_simple_constructor, and what it
simplies to is not a constructor, is_simple_constructor returns false, and
the simplifier aborts.

Jeff, please fix this.

If you have to hack up the machinery so that it looks at something,
without caring whether it actually simplifies it, make an is_simple_*
function that just returns true, and use that as the predicate.
