    * cpu-i386.c (bfd_arch_i386_fill): Updated to support multi byte
    nop instructions.
    (bfd_arch_i386_short_nop_fill): New.
    (bfd_arch_i386_long_nop_fill): Likewise.
    Use bfd_arch_i386_short_nop_fill in 32bit bfd_arch_info
    initializers.  Use bfd_arch_i386_long_nop_fill on 64bit
    bfd_arch_info initializers.

    * cpu-k1om.c (bfd_arch_i386_fill): Renamed to ...
    (bfd_arch_i386_short_nop_fill): This.
    Update bfd_arch_info initializers.
    * cpu-l1om.c: Likewise.
