Subject: [PATCH] Fix pointer to view conversion for optimized intel kernels
(#153)
Bug: `modcc` was generating invalid code when generating optimized kernels.
The optimized kernels use raw pointers instead of views, and the generated code was using view semantics.
* Use appropriate `memory::copy` invocation for the optimized kernel case.
