Subject: Re:  redundant runtime check while vectorizing

How costly would it be if we do as a first data dependence test a call
to operand_equal_p on the array references?  That certainly would
avoid lot of computations downstream in the data dependence test, but
would be applied as an initial test to all dependence relations.
