OK, I will send separate patch and turn those into identifier nodes.

It never appeared to me that I could debug them and source level :).
Compiling simple main function with profile gnerate we get:
__gcov_.main
__gcov0.main
__gcov7.main
(counters and the structure describing them)
Neither of those seems to be accessible from gdb nor we generate debug info
for the structures we finalize builtins for.
Note that with this patch and sanity check about type_stub_decl being NULL I get the following
errors and the lto-bootstrap passes (which is not too bad I would say):
