[mypyc] translate call_emit primitive ops to CallC (#9012)
Related issue: mypyc/mypyc#734
This PR translates PrimitiveOps with call_emit, which can be represented by
CallC pretty straightforwardly, to CallC. Mostly translating the description.
After this PR and another following PR which handles the ones whose
descriptions are explicitly used in irbuild, we'll able to see what's missing for
CallC by analyzing the remaining primitives.
