Details:
- Updated the test/sup source file (test_gemm.c) and Makefile to support
building matrices with small or large leading dimensions, and updated
runme.sh to support executing both kinds of test drivers.
- Updated runme.sh to allow for executing sup drivers with unpacked (the
default) or packed matrices (via setting BLIS_PACK_A, BLIS_PACK_B
environment variables), and for capturing output to files that encode
both the leading dimension (small or large) and packing status into
the filenames.
- Consolidated octave scripts in test/sup/octave_st, test/sup/octave_mt
into test/sup/octave and updated the octave code in that consolidated
directory to read the new output filename format (encoding ldim and
packing). Also added comments and streamlined code, particularly in
plot_panel_trxsh.m. Tested the octave scripts with octave 5.2.0.
- Moved old octave_st, octave_mt directories to test/sup/old.
