Patch to handle matmul(transpose(a),b)

This patch implements matmul(transpose(a),b).  However, it does not enable
vectorization even with -Ofast.

I do not intend to submit this patch in this form.

It still needs some work to create the rank-one temporary and use it,
to enable vectorization.  This is only suitable for stage 1 in gcc 7.
