0a7de0b273 Fix compilation issue with MSVC: 
MSVC always messes up with shadowed template arguments, for instance in:
  struct B { typedef float T; }
  template<typename T> struct A : B {
    T g;
  };
The type of A<double>::g will be float and not double.

441b7eaab2 Add support for non trivial scalar factor in sparse selfadjoint * dense products, and enable +=/-= assignement for such products. 
This changeset also improves the performance by working on column of the result at once.

91b3039013 Change the semantic of the last template parameter of Assignment from "Scalar" to "SFINAE" only. 
The previous "Scalar" semantic was obsolete since we allow for different scalar types in the source and destination expressions.
On can still specialize on scalar types through SFINAE and/or assignment functor.

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

2c00ac0b53 Implement generic scalar*expr and expr*scalar operator based on scalar_product_traits. 
This is especially useful for custom scalar types, e.g., to enable float*expr<multi_prec> without conversion.

8ed1553d20 bug #632: implement general coefficient-wise "dense op sparse" operations through specialized evaluators instead of using SparseView. 
This permits to deal with arbitrary storage order, and to by-pass the more complex iterator of the sparse-sparse case.
