Unfortunately, stripping the reference here...

...and then using the result for build_trait_object, loses the
difference between lvalue and rvalue references.
It should be enough to move this line up before stripping the reference.
And then you could just
datum_type = TREE_TYPE (datum_expr);
since build_trait_object will have done a convert_from_reference.
