A t2DoLoopStart are for all the low overhead loops that are not expected to change to tail predicated loop. That way we could treat them differently elsewhere in the pipeline if we need to.

That makes sense 👍 Do you envisage us moving all of the TP validation to the MVEVPTOptimisationsPass and then only doing the actual codegen in ARMLowOverheadLoops?
