This patch trivially updates various opt passes to handle DPVAssigns. In all cases, this means some combination of generifying existing code to handle DPValues and DbgAssignIntrinsics, iterating over DPValues where previously we did not, or duplicating code for DbgAssignIntrinsics to the equivalent DPValue function (in inlining and salvageDebugInfo).
