Complex type is the only TIDEAL that lack of support for all comparison operators. When rewriting constant comparison into literal node, that missing cause compiler raise an internal error. Checking the operator is available for complex type before that fix the problem. We can make this check works more generally if there's more type lack of supporting all comparison operators added, but it does not seem to be happened, so just check explicitly for complex only.
