the problem is that the C++ FE emits debug info for global using decls from
parsing:
...
#9 0x082a825e in cp_emit_debug_info_for_using (t=0xb7d6705c, context=0x0)
at /home/richard/src/trunk/gcc/cp/name-lookup.c:5223
---Type <return> to continue, or q <return> to quit---
#10 0x0829f5ef in do_toplevel_using_decl (decl=0xb7d61870, scope=0xb7d61798,
name=0xb7d66708) at /home/richard/src/trunk/gcc/cp/name-lookup.c:3360
#11 0x081bca90 in cp_parser_using_declaration (parser=0xb7cd22a4,
access_declaration_p=0 '\0')

...
via the imported_module_or_decl debug hook. I guess we should simply queue
these with the varpool. Or probably invent a new pool for just this use.
Or just weaken the sanity check.
