Ideally we'd move fold_cond_expr_with_comparison there, combining it
with operand_equal_for_comparison_p.  Not sure how this ends up
as patterns.  At least fold_cond_expr_with_comparison in isolation
looks straight-forward to convert (minus the usual STRIP_NOPs
complication involving conditional converts and constants)
