Subject: 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
