    PR13998: pretty-print bit fields numerically
    
    When a struct member has bit attributes, we should always pretty-print
    it as a number, even if the underlying type is a character.  Since these
    attributes only show up in DWARF on the member, not the type die, we
    need to treat it as a special case from the struct member iteration.
    
    * tapsets.cxx (dwarf_pretty_print::recurse_bitfield): Print the incoming
      type numerically, regardless of whether it's a char.
      (dwarf_pretty_print::recurse_struct_members): If a member has a
      bit_offset attribute, use recurse_bitfield instead of normal recurse.
    * testsuite/systemtap.printf/pretty-bits.*: Test how bitfields are
      pretty-printed, both for ints and chars underneath.
