Provide "eigen" defines to decide which instruction set is used
...
(sse3, ssse3 and sse4), independantly from the compiler.
Only those defines should be used in other places, and the user can
rely on those to know which sets are used.

using std::size_t;

For the record, here is a solution for (a*b).diagonal, at the cost of extra copies

if a and/or b as to be evaluated. So in the next commit I'll remove it. A nice
solution would be to evaluate the lhs/rhs into member of the initial product,
but that would be overkill.
