Bootstrapping with the change (crossing my finger that I won't have to remove
the definition of df_simulate_find_noclobber_defs!-). Allow for 3h30 to pass
the critical point and over 5h to complete the bootstrap.

With the faulty cc1, the following trivial test ICE at -O1
int
main ()
{
;
return 0;
}
What would you need?
