Hi,
no need to test a phi argument with itself (testing arg0 != arg1 is not
the right test, though, so remembering the candidate index):

Since we have the alias oracle we no longer optimize the testcase below
because I initially restricted the stmt walking to give up for PHIs
with more than 2 arguments because of compile-time complexity issues.
But it's easy to see that compile-time is not an issue when we
reduce PHI args pairwise
