I like the change you've made here to put the value twiddling in
md_apply_fix for both insn and data relocs in one place (field_value).
I'm not so sure about trying to merge the bfd_reloc_type_lookup from
md_assemble.  We don't currently need the "howto" in md_apply_fix, so
that seems like doing unnecessary work.
