Thank you, @offamitkumar 
I looked on `runtime_call_w_cp_type` related code for s390 and it is not simple. Refactoring it will take more changes than current PR. It seems `CodeBlob::ctable_begin()` can be also removed.

I suggest to file followup RFE to make such changes so that this PR will not need to wait for them.
