Committed as rev.  248425.

Thanks for the review!

I am going to close PR 66094 now.  Any other cases
would be silly.  With a vector v and a matrix a,

matmul(transpose(a),v) can be replaced by matmul(v,a)
matmul(v,transpose(a)) can be replaced by matmul(a,v)

And as for matmul(transpose(a), transpose(b)), well...
