670d56441c PR 544: Set requestedAlignment correctly for SliceVectorizedTraversals 
Commit aa110e681b
 optimised the multiplication of small dyanmically
sized matrices by restricting the packet size to a maximum of 4, increasing
the chances that SIMD instructions are used in the computation.  However, it
introduced a mismatch between the packet size and the requestedAlignment.  This
mismatch can lead to crashes when the destination is not aligned.  This patch
fixes the issue by ensuring that the AssignmentTraits are correctly computed
when using a restricted packet size.
* * *
Bind LinearPacketType to MaxPacketSize

This commit applies any packet size limit specified when instantiating
copy_using_evaluator_traits to the LinearPacketType, providing that the
size of the destination is not known at compile time.
* * *
Add unit test for restricted packet assignment

A new unit test is added to check that multiplication of small dynamically
sized matrices works correctly when the packet size is restricted to 4 and
the destination is unaligned.

A true error will triggered only if std::foo works but our numext::foo fails.
