The granularity of AArch64 relocs varies, but the smallest is one
byte.  We don't use format() for anything.  (Perhaps we should, as it
would make the gnarly code that handles relocs simpler and faster, but
that's for another day.)

So this is what I've ended up with:

  29   // machine-dependent parts of class relocInfo
  30  private:
  31   enum {
  32     // Relocations are byte-aligned.
  33     offset_unit        =  1,
  34     // We don't use format().
  35     format_width       =  0
  36   };
