The fix for https://github.com/openjdk/valhalla/pull/1981 introduced a regression in type-class mediated attribution of shift operators. The test for such operators should only check for reference-ness of the first operand (the one that might potentially be a type class). Shift operators are "weird" in that they are not symmetric -- first operand is T, second operand is `int` -- and that leads to issue. The code before https://github.com/openjdk/valhalla/pull/1981 took this into account, but unfortunately the workaround was reverted by accident.
