Why is this not a method on `CastOperation`?


================
Comment at: lib/Sema/SemaCast.cpp:2288
+      SrcType->isPointerType()) {
+    const PointerType *DestPtr = DestType->getAs<PointerType>();
+    if (!DestPtr->isAddressSpaceOverlapping(*SrcType->getAs<PointerType>())) {
----------------
Please test the result of `getAs` instead of separately testing `isPointerType`.

Why is this check OpenCL-specific?  Address spaces are a general language feature.
