Any pointer captured into the SYCL kernel lamba will fail when dereferenced ... except USM. If it weren't for USM we could just emit a deferred diagnostic for every pointer capture. Instead, we attempt to identify which pointers are USM, and which are definitely not. For those that are definitely not, we emit an error diagnostic, which also instructs the developer to use USM. For those pointer captures that are unknown, we emit a note suggesting that the developer ensure they are using USM. For captured pointer expressions that are identified as USM, we do nothing.
