When not optimizing, use the number of hashed symbols rather than
dynsymcount.
(bfd_elf_size_dynamic_sections): Only add DT_HASH if info->emit_hash,
and ADD DT_GNU_HASH if info->emit_gnu_hash.

adjust compute_bucket_count caller.  Create and populate .gnu.hash
section if info->emit_gnu_hash.
(elf_link_output_extsym): Only populate .hash section if
finfo->hash_sec != NULL.

set_gdbarch_deprecated_register_byte.  Do call set_gdbarch_return_value
instead of set_gdbarch_deprecated_use_struct_convention,
set_gdbarch_extract_return_value, set_gdbarch_store_return_value,
or set_gdbarch_deprecated_extract_struct_value_address.
* alphafbsd-tdep.c (alphafbsd_return_in_memory): Rename from
alphafbsd_use_struct_convention, remove gcc_p argument.
