Perspectives in the OOB module

[OlivierBBB]

Main point

Given the number of instructions that the OOB module deals with (and the 8 = 1 + 7 new BLS precompile related instructions) the OOB module could start using perspectives. We would require the following perspectives columns

MACRO
SCENARIO
COMPUTATION

We may split SCENARIO further and have e.g. SCENARIOS_OPC / SCENARIOS_PRC / SCENARIOS_BLS columns or any other splitting that makes sense.

Structure

The internal transitions would be

PADDING+ INSTRUCTION_PROCESSING*

where INSTRUCTION_PROCESSING is

MACRO        [1 row]
SCENARIO_XXX [1 row]
COMPUTATION  [ct_max rows]

Lookups

We would further have room to have WCP and EUC lookup columns to live side by side as in #141 (if we want to.) Indeed we require 6 = I + 2 + 2 + 1 WCP columns (instruction, 1st argument, 2nd argument, result) and 3 = 1 + 1 + 1 EUC columns (arg 1, arg 2, res) and with the latest OOB instruction (for CREATE post EIP-3860, see #59) we have 10 OOB_DATA_k columns, plus the OOB_INST etc ...
