compiler: ignore function type result name in export data

This change ensures that we never output a result name in the export
data if there is only a single result.  Previously we would output a ?
if the single result had a name.  That made the output unstable,
because the hashing ignores the result name, so whether we output a ?
or not depended on how equal hash elements were handled.
