	first free position, if any.  Adjust call to self.  Use a single field
	directly only if it hasn't got a representation clause or is placed at
	offset zero.  Create the variant part at offset 0 if all the fields
	down to this level have a rep clause.  Do not chain the variant part
	immediately and adjust downstream.
	Do not test ALL_REP before moving the fields without rep clause to the
	previous level.  Call create_rep_part to create the REP part and force
	a minimum size on it if necessary.  Do not chain it immediately.
	Create a fake REP part if there are fields without rep clause that need
	to be laid out starting from FIRST_FREE_POS.
	At the end, chain the REP part and then the variant part.
	(create_rep_part): New function.
	(get_rep_part): Minor tweak.
