lto.c (lto_materialize_function): Announce function when reading body...
* lto.c (lto_materialize_function): Announce function when
reading body; allocate_struct_function only when reading body;
do not finalize local statics; ggc_collect after reading;
do not mark reachable node.
(materialize_cgraph): Do not announce function.
