Richard SmithandJon Ross-Perkins efea072be3 Compute specific constant values. (#4128) 
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.
