symtab.c (symtab_node::verify_base): Verify body_removed->!definiton
* symtab.c (symtab_node::verify_base): Verify body_removed->!definiton
* lto-cgraph.c (lto_output_varpool_node): Do not keep definition of
variables in boundary that have no inlitalizer encoded and are
not aliases.
* varasm.c (default_binds_local_p_2): External definitions do not
count as definitions here.
