DECL_INITIAL being NULL has *always* meant that the variable goes
in BSS, and thus is zero initialized. We're talking about loading
from static, read-only memory. There must be *SOME* value there,
and by definition it cannot change.
You've not yet explained to me what is wrong with assuming zero
from null DECL_INITIAL. How about you start there?
