This only creates one even if type declarations are from different CUs. The definition DIE lookup mechanism is the same as before, via manual index, which is able to search cross CUs. We check if a type is created before using the `UniqueDWARFASTTypeMap` as before: For C++, unique type is identified by full qualified name + byte size. For other languages, it's base name + byte size + declaration location.
