f737536744 fix NEON port, use vget_lane_*() instead of temporary variables (saves extra 
load/store), following advice by  Josh Bleecher Snyder <josharian@gmail.com>.
Also implement pmadd() using vmla instead of nested padd/pmul.

746378868a 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

d0b873822f 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()

2393ceb380 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.

c1eb820e50 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.

069fd0e4be 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.
