Summary: Diagnostic is emitted if some declaration of unsupported type declaration is used inside device code. Memcpy operations for structs containing member with unsupported type are allowed. Fixed crash on attempt to emit diagnostic outside of the functions. The approach is generalized between SYCL and OpenMP. CUDA/OMP deferred diagnostic interface is going to be used for SYCL device.
