c++: missing dtor with -fno-elide-constructors [PR100838]

tf_no_cleanup only applies to the outermost TARGET_EXPR, and we already
clear it for nested calls in build_over_call, but in this case both
constructor calls came from convert_like, so we need to clear it in the
recursive call as well.  This revealed that we were adding an extra
ck_rvalue in direct-initialization cases where it was wrong.
