Ayal Zaks e498be5738 [LV] Strip wrap flags from vectorized reductions ...

A sequence of additions or multiplications that is known not to wrap, may wrap
if it's order is changed (i.e., reassociated). Therefore when vectorizing
integer sum or product reductions, their no-wrap flags need to be removed.
