ffe6d1f901 Alignment fixes: 
* Fix AlignedBit computation for Plain Objects
 * use it for the conditional alignment of operator new
 * only overload new in PlainObjectBase, don't overload again in Matrix and Array

bc6d78982f Bugs 157 and 377 - General tightening/testing of vectorwise ops: 
* add lots of static assertions making it very explicit when all these ops
are supposed to work:
** all ops require the rhs vector to go in the right direction
** all ops already require that the lhs and rhs are of the same kind
(matrix vs vector) otherwise we'd have to do complex work
** multiplicative ops (introduced Kibeom's patch) are restricted to arrays, if only because for matrices they could be ambiguous.

* add a new test, vectorwiseop.cpp.

* these compound-assign operators used to be implemented with for loops:

   for(Index j=0; j<subVectors(); ++j)
     subVector(j).array() += other.derived().array();

This didn't seem to be needed; replaced by using expressions like operator+ and operator- did.

3e4a68cc60 optimize vectorized reductions by peeling the loop: 
- x2 for squaredNorm() on double
 - peeling the loop with a peeling factor of 4 leads to even better perf
   for large vectors (e.g., >64) but it makes more difficult to keep good performance on smaller ones.
