It's mostly
a) target specific builtin types and decls that do not get fixed up
b) LTO (or rather generic) builtin functions and types not get fixed up
c) the tree.c local canonical type machinery that isn't giving the same
answer as gimple_register_type () does.
with that "fixed" the sanity-checking patch works fine.
For a more proper patch I have to think about the tree.c type hashing
and unification some more.
