When forming a specific (previously called a generic instance), evaluate the eval block of the generic to determine the values of any constants used in that specific. The majority of the work here is updating eval.cpp so that it can use the results of prior evaluations in the same block when computing later values. Include the computed results in the formatted SemIR output. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
