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.
