lto-symtab.c (lto_symtab_free): New function.
* lto-symtab.c (lto_symtab_free): New function.
* lto-streamer.h (lto_symtab_free): Declare.
* lto-cgraph.c (reachable_from_other_partition_p): Export; do not assume
that if function is needed it is reachable.
(lto_output_node): See if it the function is reachable or referenced.
(output_cgraph): Update call of lto_output_node.
* lto-streamer.h (reachable_from_other_partition_p): Declare.
* lto.c (lto_fixup_decls): Free no longer needed lto_global_var_decls
vector.
* lto.c (lto_1_to_1_map): Remove some no longer needed checks.
(lto_promote_cross_file_statics): Never promote DECL_EXTERNAL;
use reachable_from_other_partition_p and
referenced_from_other_partition_p test.
