Enhance the disassembler so that it will reliably determine whether a reloc applies to the middle of the next insn.
PR 24907
binutils* objdump.c (null_print): New function.
(disassemble_bytes): Delete previous_octets local and replace with
a test of the max_reloc_offset_into_insn field of the
bfd_arch_info structure. If a reloc is a potential match for the
next insn, then perform a dummy disassembly in order to calculate
its real length.
bfd * archures.c (bfd_arch_info_type): Add max_reloc_offset_into_insn
field.
(bfd_default_arch_struct): Initialise the new field.
