So the built-ins would take address of this decl, something else?
Perhaps address, perhaps just referenced uninitialized?
True, assuming no pass would actually want to change that SSA_NAME of the
magic decl just because it is undefined (coalesce with some other undefined
SSA_NAME or something similar). I hope nothing does that, it would be
problematic for the uninitialized warning pass too I bet.
Boo hiss! I've seen uninitialized variables cause all sorts of grief
when cleaning up SSA.
