This adds support for DW_IDX_parent. If DIE has a parent then DW_IDX_parent in Entry will point to Entry for that parent DIE. Otherwise it will have DW_FORM_flag_present in abbrev. Which takes zero space in Entry. This came from https://discourse.llvm.org/t/rfc-improve-dwarf-5-debug-names-type-lookup-parsing-speed/74151
