ECCVM currently supports only eq or only reset ops

[maramihali]

ECCVM was designed to support opcode value 1 and 2 - this translates to only reset or only eq. These were seen as potential optimisation in relation to ZeroMorph. However, we've evolved to see these two ops only as combined (opcode value 3) and ultra ops has support for only eq_and_reset. This is an inconsistency between Ultra and ECCVM ops that should be addressed and has the potential to simplify some ECCVM relations.

@notnotraju can we close this issue?

Not worth the effort we've decided
