    PR3498: speed up pass-2 and pass-3 for kernel offline dwfl module searching
    
    * dwflpp.cxx (dwflpp ctor): Parametrize for user/kernel modes.
      Update callers.
      (dwfl_report_offline_predicate): New function.  Filter and
      abort searches early if possible.
      (setup_kernel): Use new predicate.
    * dwflpp.h: Corresponding changes.
    * tapsets.cxx (dwfl_report_offline_predicate): Remove this shared
      implementation.
      (dwarf_builder): Turn kern_dw into module_name->dwflpp* map, just
      like user_dw.
      (get_kern_dw): Adapt.
      (dwarf_build_no_more): Adapt.
    * tapsets.h: Remove old shared predicate.
    * translate.cxx (dwfl_report_offline_predicate2): New function.
      Filter and abort searches early if possible.
      (emit_symbol_data): Use it.
