[committed 05/12] d: Use Identifier::idPool to generate anonymous field name.

[Iain Buclaw via Gcc-patches]

The self-hosted implementation of the D front-end does not export
Identifier::generateId, so handle name generation inline instead.

gcc/d/ChangeLog:

        * d-builtins.cc (build_frontend_type): Use Identifier::idPool to
        generate anonymous field name.
