Eliminate compiler warnings from IA-64 port.
* coff-ia64.c (howto_table): Use EMPTY_HOWTO. (in_reloc_p): Add ATTRIBUTE_UNUSED to unused parameters. * cpu-ia64-opc.c (ins_rsvd, ext_rsvd, ins_const, ext_const): Likewise. (ins_imms_scaled): Initialize sign_bit at function entry. (elf64_ia64_operands): Add missing initializers. * elfxx-ia64.c (elfNN_ia64_reloc, elfNN_ia64_reloc_type_lookup, elfNN_ia64_info_to_howto, elfNN_ia64_fake_sections, elfNN_ia64_add_symbol_hook, elfNN_ia64_is_local_label_name, elfNN_ia64_local_hash_table_init, get_fptr, get_pltoff, elfNN_ia64_adjust_dynamic_symbol): Add ATTRIBUTE_UNUSED for unused parameters. (elfNN_ia64_info_to_howto): Initialize free_relocs, free_contents, and free_extsyms at function entry. (elfNN_add_symbol_hook): Add unsigned cast to bfd_get_gp_size result. (elfNN_ia64_create_dynamic_sections): Delete unused local h. (get_got): Delete unused local srel. (elfNN_ia64_check_relocs): Initialize dynrel_type when declared. (elfNN_ia64_relocate_section): Delete unused local dynindx.
