Subject: [PATCH] Pass field information (shape,stride) as single elements
instead of arr
- small (length < 5) arrays with shape and stride information had to be
memcpy'd to the GPU before every kernel call
- instead of passing the information as arrays, the single elements are
passed
- leads to more function arguments, but simplifies GPU kernel calls
-> changes in all backends required
