Gold version of a4b6fadd. Don't emit long branch or plt branch stubs

(Target_powerpc::Branch_info::make_stub): Determine whether long
branch stub is for save/restore function.

(Stub_table:clear_stubs): Clear need_save_res_.
(Stub_table:set_address_and_size): Add save/restore section size.
(Stub_table::add_long_branch_entry): Add save_res param. Set
need_save_res_, but don't add space for save/restore stubs.
(Stub_table::find_long_branch_entry): Return offset to local copy
of save/restore func.
(Stub_table::do_write): Don't output save/restore stubs. Instead
copy the save/restore functions.
