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.
