Hello world,

after the recent discussion about MATMUL(A,TRANSPOSE(B)) I have prepared
a patch which implements this.

The patch is a rather straightforward implementation using the machinery
that is already in place for matmul inlining, so the risk of introducing
a regression should be quite low.

Because of this, and beacuse this is a significant use case, I think
this could still be OK for trunk.  Jerry already indicated in the PR
that this could be the case.

Regression-tested.

So... comments?  Toon, would this help you?  Could yo maybe give this
a spin?

Regards

	Thomas
