After thinking about this a bit more, the code here was too
conservative. We know that everything but an object is going to
throw, so it's sufficient to restrict the type to MAY_BE_OBJECT.
The change in the test is weird but not incorrect, because it
operates on empty inferred types, in which case the code must be
dead (which it is). We should probably add a more explicit removal
of code working on empty types.
