  [lldb] Improve invalid DWARF DW_AT_ranges error reporting

In D98289#inline-939112 @dblaikie said:
  Perhaps this could be more informative about what makes the range list
  index of 0 invalid? "index 0 out of range of range list table (with
  range list base 0xXXX) with offset entry count of XX (valid indexes
  0-(XX-1))" Maybe that's too verbose/not worth worrying about since
  this'll only be relevant to DWARF producers trying to debug their
  DWARFv5, maybe no one will ever see this message in practice. Just
  a thought.
