Description

We now have two ways of clock-gating a register, a `seq.compreg.ce` and `seq.clock_gate`+`seq.compreg`. Is there any merit to having both, or should `seq.compreg.ce` be removed in favor of the latter option?

Research direction

Compare the two clock-gating approaches named in the issue: seq.compreg.ce and seq.clock_gate combined with seq.compreg. Review their intended semantics and existing uses before deciding whether both should remain. Done means establishing a canonical approach and resolving whether seq.compreg.ce should be removed.
