summary:     Move (part of) evaluation of products to evaluator objects.
* Copy implementation from CoeffBasedProduct.
* Copy implementation from GeneralProduct in InnerProduct case.
* For GeneralProduct in other cases, call the evalTo() member function with
  expression objects in constructor of evaluator.

changeset:   34907ca1cccd
user:        jitseniesen
date:        2012-06-29 14:24:04
summary:     Implement interface for NoAlias assignments.
* Rename the old copy_using_evaluators to noalias_copy_using_evaluators.
* Write a new copy_using_evaluators which strips NoAlias expression, if present,
  and calls noalias_copy_using_evaluators; in future, it will also take care of
  aliasing in products.
* Add expression() getter to NoAlias.

changeset:   86f994573a14
user:        jitseniesen
date:        2012-06-29 14:32:12
summary:     Implement eval-at-once in evaluator.
- Add evaluator_traits with HasEvalTo flag, which is true if evaluator
  has evalTo() function.
- Add AllAtOnce traversal, which calls evalTo() in evaluator.
- If source evaluator in copy_using_evaluator has HasEvalTo set, then
  use AllAtOnce traversal.

changeset:   755bfe931ed6
user:        jitseniesen
date:        2012-06-29 14:49:25
summary:     Make product eval-at-once.
* Make product EvalAtOnce in cases OuterProduct, GemmProduct and
  GemvProduct
* Ensure that product evaluators are nested inside EvalToTemp
  evaluator
* As temporary kludge, evaluate expression to temporary in AllAtOnce
  traversal and pass expression operator to evalTo()

changeset:   178f7f2e8375
user:        jitseniesen
date:        2012-06-29 14:54:09
summary:     Implement A.noalias() = B * C without temporaries
* Wrap expression inside EvalToTemp in copy_using_evaluators() if we
  assume aliasing for that expression (that is, for products)
* Remove temporary kludge of evaluating expression to temporary in
  AllAtOnce traversal
* Implement EvalToTemp expression object
