        Merged CAST branch.

        Changes since -cast.8:
        * separated usage of object and values types;
        * fixed warning and error reports for compile-time type
          errors;
        * inline structure slot accessors are implemented with source
          transforms;
        * enabled warning emitting for type errors in some paths to
          CAST;
        * removed check for type errors in arguments of a call of a
          flushable function;
        * source transforms are made nameless.
