[GOLD] PowerPC64 @notoc in non-power10 code
Gold version of commit 7aba54da42. elfcpp/ * powerpc.h (R_PPC64_REL24_P9NOTOC): Define. gold/ * powerpc.cc (Target_powerpc::maybe_skip_tls_get_addr_call, is_branch_reloc, max_branch_delta): Handle R_PPC64_REL24_P9NOTOC. (Target_powerpc::Branch_info::make_stub): Likewise. (struct Plt_stub_ent): Add p9notoc_, p9off_, tsize_. (struct Branch_stub_ent): Add p9notoc_, p9off_. (Stub_table::add_plt_call_entry): Handle R_PPC64_REL24_P9NOTOC. (Stub_table::add_long_branch_entry): Likewise. (Stub_table::add_eh_frame): Likewise. (Stub_table::plt_call_size): Return aligned size. Adjust callers. Handle p9notoc_ sizing. (Stub_table::do_write): Write out p9notoc_ stubs. (Target_powerpc::Scan::get_reference_flags, local, global): Handle R_PPC64_REL24_P9NOTOC. (Target_powerpc::Relocate::relocate): Likewise.
