[ARM] Don't mark vctp as having sideeffects

Authored by dmgreen on Wed, Jul 15, 2:20 PM.



As far as I can tell, it should not be necessary for VCTP to be unpredictable in tail predicated loops. Either it has a a valid loop counter as a operand which will naturally keep it in the right loop, or it doesn't and it won't be converted to a tail predicated loop. Not marking it as having side effects allows it to be scheduled more cleanly for cases where it is not expected to become a tail predicate loop.
