* class.c (add_method): Build up OVERLOADs properly for conversion ops.
	* search.c (lookup_conversions): Handle getting real OVERLOADs.
	(add_conversions): Likewise.  Revert last change.
	* call.c (add_conv_candidate): Pass totype to add_candidate instead
	of fn.  Don't add a new candidate if the last one was for the same
	type.
	(print_z_candidates): Handle getting a type as a function.
	(joust): If we got two conversion candidates to the same type,
	just pick one.
	(build_object_call): Lose 'templates'.
	(build_user_type_conversion_1): Handle getting real OVERLOADs.
Fixes g++.jason/overload7.C.
