eb621413c1 Revert vec/y to vec*(1/y) in row-major TRSM: 
- div is extremely costly
- this is consistent with the column-major case
- this is consistent with all other BLAS implementations

0db6d5b3f4 bug #1356: fix calls to evaluator::coeffRef(0,0) to get the address of the destination 
by adding a dstDataPtr() member to the kernel. This fixes undefined behavior if dst is empty (nullptr).

e3f613cbd4 Improve performance of row-major-dense-matrix * vector products for recent CPUs. 
This revised version does not bother about aligned loads/stores,
and rather processes 8 rows at ones for better instruction pipelining.

6a5fe86098 Complete rewrite of column-major-matrix * vector product to deliver higher performance of modern CPU. 
The previous code has been optimized for Intel core2 for which unaligned loads/stores were prohibitively expensive.
This new version exhibits much higher instruction independence (better pipelining) and explicitly leverage FMA.
According to my benchmark, on Haswell this new kernel is always faster than the previous one, and sometimes even twice as fast.
Even higher performance could be achieved with a better blocking size heuristic and, perhaps, with explicit prefetching.
We should also check triangular product/solve to optimally exploit this new kernel (working on vertical panel of 4 columns is probably not optimal anymore).

a91de27e98 Fix compilation issue with MSVC: 
MSVC always messes up with shadowed template arguments, for instance in:
  struct B { typedef float T; }
  template<typename T> struct A : B {
    T g;
  };
The type of A<double>::g will be float and not double.
