  Reapply [ConstantFold] Avoid creation of undesirable binop

This was reverted together with another commit due to a test
conflict. Reapply without functional changes.

-----

When commuting the operands, don't create a constant expression
for undesirable binops. Only invoke the constant folding function
in that case.
