apex fails to generate correct matmul() code for Wave Motion benchmark

[bernecky]

apex commit 9e60f08
generates TRANSPOSE matrix multiply code for waver.sac, here:

~/apexgit/Ancillary/benchmks/WaveMotion/waver

It should be generating the STAR algorithm code.

I will fix this.

The current inner product code in sac/fragments/dconj.frg does not support left argument
rank>2, so we generate the TRANSPOSE algorithm.
