So what happens here is that normally we initialize the builtins via
c_common_nodes_and_builtins, which has:
5711 if (!flag_preprocess_only)
5712 c_define_builtins (va_list_ref_type_node, va_list_arg_type_node);
c_define_builtins defines builtins in builtins.def, that includes even
sanitizer.def. I guess that flag_preprocess_only was in effect due to PCH
and we didn't define the builtins. I still haven't managed to create
some sweet & small testcase, but I've found another ICE with PCH:
What doesn't make sense to me is I don't see where PCH sets
flag_preprocess_only. If you can point me to where that happens, then I
think we'd just need a comment that PCH turns on flag_preprocess_only,
which guards the creation of some builtins.
