        * godump.c (precision_to_units): New helper function.

        (go_format_type): Represent unions with an array of uints of the size
        of the alignment in go.  This fixes the 'random' size of the union's
        representation using just the first field.
        (go_format_type): Add argument that indicates whether a record is
        nested (used for generation of artificial go names).

        (go_output_var): Prefer to output type as alias (typedef).
        (go_format_type): Bitfields in records are simulated as arrays of bytes
        in go.

        * godump.c (go_format_type): Fix handling of arrays with zero elements.
