The three hazards here are false positives: the Object* bits will never be non-null in these stack uses, so the barriers /should/ never fire. The analysis, for obvious reasons of sanity, is not so clever. It (correctly) sees ~TypeRepresentation as a use of the contained object*. I think we should use scoping here to ensure that these stack TypeReprs are *obviously* not live across a GC.
