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.

db36e4204f [Geometry/AlignedBox] New typedefs, like for Core/Matrix 
Includes 1-4 and dynamic sized boxes for int, float and double type.
Also changes the tests to use these typedefs.

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.

ab3f138b23 In the Matrix constructor taking (rows, cols), statically assert that the types are integer. 
The 2D vector ctor taking (x, y) is not concerned.

9df2f5c923 bug #369 - Quaternion alignment is broken 
The problem was two-fold:
 * missing aligned operator new
 * Flags were mis-computed, the Aligned constant was misused

16b638c159 Throw std::bad_alloc even when exceptions are disabled, by doing new int[size_t(-1)]. 
Don't throw exceptions on aligned_malloc(0) (just because malloc's retval is null doesn't mean error, if size==0).
Remove EIGEN_NO_EXCEPTIONS option, use only compiler standard defines. Either exceptions are enabled or they aren't.
