PR10594: Provide a cached dwarf_getscopes_die
This avoids repeated DIE traversal by caching all parents on the first
call, so future calls are just a simple walk up parent links.
* dwflpp.cxx (dwflpp::getscopes_die): New cached function that mimics
libdw's dwarf_getscopes_die using cached parent links.
(dwflpp::cache_die_parents): New function to build the parent cache.
(dwflpp::~dwflpp): Clean up the parent caches.
(dwflpp::iterate_over_labels): Use the cached getscopes_die.
(dwflpp::find_variable_and_frame_base): Ditto.
* tapsets.cxx (dwarf_derived_probe::saveargs): Ditto.
(uprobe_derived_probe::saveargs): Ditto.
(dwarf_var_expanding_visitor::visit_target_symbol_context): Ditto.
