This is done by decomposing the constant instruction into its operands, substituting into the operands, and then rebuilding the constant value by invoking the constant evaluator. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com> Co-authored-by: Carbon Infra Bot <carbon-external-infra@google.com>
