Bug 29829 - dwarf-reader: Allow DIEs to be in a lexical block
Normally, ABI-relevant DWARF DIEs (types and decls) should be at
namespace level. There are real-life cases where such a DIE might be
defined in a lexical block.
This patch teaches the DWARF reader to handle such cases.
* src/abg-dwarf-reader.cc (get_scope_for_die): Support
DW_TAG_lexical_block as DIE scope.
