85699850d9 Add missing CUDA kernel to tensor scan op 
The TensorScanOp implementation was missing a CUDA kernel launch.
This adds a simple placeholder implementation.

75c333f94c Don't store the scan axis in the evaluator of the tensor scan operation since it's only used in the constructor. 
Also avoid taking references to values that may becomes stale after a copy construction.

66e99ab6a1 Relax mixing-type constraints for binary coefficient-wise operators: 
- Replace internal::scalar_product_traits<A,B> by Eigen::ScalarBinaryOpTraits<A,B,OP>
- Remove the "functor_is_product_like" helper (was pretty ugly)
- Currently, OP is not used, but it is available to the user for fine grained tuning
- Currently, only the following operators have been generalized: *,/,+,-,=,*=,/=,+=,-=
- TODO: generalize all other binray operators (comparisons,pow,etc.)
- TODO: handle "scalar op array" operators (currently only * is handled)
- TODO: move the handling of the "void" scalar type to ScalarBinaryOpTraits
