Added libxsmm support to test/sup drivers.
Details: - Modified test/sup/Makefile to build drivers that test the performance of skinny/small problems via libxsmm. - Modified test/sup/runme.sh to run aforementioned drivers. - Modified test/sup/test_gemm.c so that problem sizes are tested in reverse order (from largest to smallest). This can help avoid certain situations where the CPU frequency does not immediately throttle up to its maximum. Thanks to Robert van de Geijn for recommending this fix.
