This simplifies the core benefit of -flimit-debug-info by taking a more systematic approach to avoid emitting debug info definitions for types that only require declarations. The previous ad-hoc approach (3 cases removed in this patch) had many holes. The general approach (adding a bit to TagDecl and callback through ASTConsumer) has been discussed with Richard Smith - though always open to revision. llvm-svn: 186262
