Details: - Use compile-time implementations of Eigen in test_gemm.c via new EIGEN cpp macro, defined on command line. (Linking to Eigen's BLAS library is not necessary.) However, as of Eigen 3.3.7, Eigen only parallelizes the gemm operation and not hemm, herk, trmm, trsm, or any other level-3 operation. - Fixed a bug in trmm and trsm drivers whereby the wrong function (bli_does_trans()) was being called to determine whether the object for matrix A should be created for a left- or right-side case. This was corrected by changing the function to bli_is_left(), as is done in the hemm driver. - Added support for running Eigen test drivers from runme.sh.
