Correctly handle modules that export methods/field names, but not their corresponding class/type. Do this by accumulating these 'orphan' exports in a separate list during traversal of the export list in checkExport().

These delayed exports are then afterwards added to the export list
entry for their parent class/type, but only if that entity is already
exported.
