blis/test/supmt/test_gemm.c
Field G. Van Zee 1a284828d1 Support multithreading within the sup framework. 
Details:
- Added multithreading support to the sup framework (via either OpenMP
  or pthreads). Both variants 1n and 2m now have the appropriate
  threading infrastructure, including data partitioning logic, to
  parallelize computation. This support handles all four combinations
  of packing on matrices A and B (neither, A only, B only, or both).
  This implementation tries to be a little smarter when automatic
  threading is requested (e.g. via BLIS_NUM_THREADS) in that it will
  recalculate the factorization in units of micropanels (rather than
  using the raw dimensions) in bli_l3_sup_int.c, when the final
  problem shape is known and after threads have already been spawned.
- Implemented bli_?packm_sup_var2(), which packs to conventional row-
  or column-stored matrices. (This is used for the rrc and crc storage
  cases.) Previously, copym was used, but that would no longer suffice
  because it could not be parallelized.
- Minor reorganization of packing-related sup functions. Specifically,
  bli_packm_sup_init_mem_[ab]() are called from within packm_sup_[ab]()
  instead of from the variant functions. This has the effect of making
  the variant functions more readable.
- Added additional bli_thrinfo_set_*() static functions to bli_thrinfo.h
  and inserted usage of these functions within bli_thrinfo_init(), which
  previously was accessing thrinfo_t fields via the -> operator.
- Renamed bli_partition_2x2() to bli_thread_partition_2x2().
- Added an auto_factor field to the rntm_t struct in order to track
  whether automatic thread factorization was originally requested.
- Added new test drivers in test/supmt that perform multithreaded sup
  tests, as well as appropriate octave/matlab scripts to plot the
  resulting output files.
- Added additional language to docs/Multithreading.md to make it clear
  that specifying any BLIS_*_NT variable, even if it is set to 1, will
  be considered manual specification for the purposes of determining
  whether to auto-factorize via BLIS_NUM_THREADS.
- Minor comment updates.
