[GOLD] Power10 stub selection
gold version of commit e10a07b32dc1. * options.h (DEFINE_enum): Add optional_arg__ param, adjust all uses. (General_options): Add --power10-stubs and --no-power10-stubs. * options.cc (General_options::finalize): Handle --power10-stubs. * powerpc.cc (set_power10_stubs): Don't set when --power10-stubs=no. (power10_stubs_auto): New. (struct Plt_stub_ent): Add toc_ and tocoff_. Don't use a bitfield for indx_. (struct Branch_stub_ent): Add toc_and tocoff_. Use bitfields for iter_, notoc_ and save_res_. (add_plt_call_entry): Set toc_. Adjust resizing conditions for --power10-stubs=auto. (add_long_branch_entry): Set toc_. (add_eh_frame, define_stub_syms): No longer use const_iterators for plt and long branch stub iteration. (build_tls_opt_head, build_tls_opt_tail): Change parameters and return value. Move tests for __tls_get_addr to callers. (plt_call_size): Handle --power10-stubs=auto. (branch_stub_size): Likewise. (Stub_table::do_write): Likewise. (relocate): Likewise.
