Push name onto *converter-types* in expanded form
Push name onto *converter-types* in expanded form

Push the name of the structure onto *converter-types* in defconvert in
the macroexpansion so that when the expanded form is run,
*converter-types* will be correct.  Previously, it only pushed the
name at macroexpand time, so that the converter was known only in
sessions which included compilation.
