[TTI] Consider select form of and/or i1 as having arithmetic cost This is a patch that updates the cost of `select i1 a, b, false` to be equivalent to that of `and i1 a, b` as well as the cost of `select i1 a, true, b` equivalent to `or i1 a, b`. Until now, these selects were folded into and/or i1 by InstCombine, but the transformation is poison-unsafe. This is a step towards removing the unsafe transformation. D93065 has relevant transformations linked. These selects should be translated into the assemblies as and/or i1 do in the same manner. The cost should be equivalent.
