operand_equal_p is reasonably cheap.

Subject: Re: redundant runtime check while vectorizing
Here is a patch for this:
> a first data dependence test a call to operand_equal_p on the array references
Tested with vect.exp and tree-ssa.exp.
I will send another

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

I belive this is a known issue with the data-dependence analyzer? (I never
understood why it doesn't recognize identical references...)
