Field G. Van Zee 88ad841434 Squash-merge 'pr' into 'squash'. (#457)
Merged contributions from AMD's AOCL BLIS (#448).
  
Details:
- Added support for level-3 operation gemmt, which performs a gemm on
  only the lower or upper triangle of a square matrix C. For now, only
  the conventional/large code path will be supported (in vanilla BLIS).
  This was accomplished by leveraging the existing variant logic for
  herk. However, some of the infrastructure to support a gemmtsup is
  included in this commit, including
  - A bli_gemmtsup() front-end, similar to bli_gemmsup().
  - A bli_gemmtsup_ref() reference handler function.
  - A bli_gemmtsup_int() variant chooser function (with variant calls
    commented out).
- Added support for inducing complex domain gemmt via the 1m method.
- Added gemmt APIs to the BLAS and CBLAS compatiblity layers.
- Added gemmt test module to testsuite.
- Added standalone gemmt test driver to 'test' directory.
- Documented gemmt APIs in BLISObjectAPI.md and BLISTypedAPI.md.
- Added a C++ template header (blis.hh) containing a BLAS-inspired
  wrapper to a set of polymorphic CBLAS-like function wrappers defined
  in another header (cblas.hh). These two headers are installed if
  running the 'install' target with INSTALL_HH is set to 'yes'. (Also
  added a set of unit tests that exercise blis.hh, although they are
  disabled for now because they aren't compatible with out-of-tree
  builds.) These files now live in the 'vendor' top-level directory.
- Various updates to 'zen' and 'zen2' subconfigurations, particularly
  within the context initialization functions.
- Added s and d copyv, setv, and swapv kernels to kernels/zen/1, and
  various minor updates to dotv and scalv kernels. Also added various
  sup kernels contributed by AMD to kernels/zen/3. However, these
  kernels are (for now) not yet used, in part because they caused
  AppVeyor clang failures, and also because I have not found time to
  review and vet them.
- Output the python found during configure into the definition of PYTHON
  in build/config.mk (via build/config.mk.in).
- Added early-return checks (A, B, or C with zero dimension; alpha = 0)
  to bli_gemm_front.c.
- Implemented explicit beta = 0 handling in for the sgemm ukernel in
  bli_gemm_armv7a_int_d4x4.c, which was previously missing. This latent
  bug surfaced because the gemmt module verifies its computation using
  gemm with its beta parameter set to zero, which, on a cortexa15 system
  caused the gemm kernel code to unconditionally multiply the
  uninitialized C data by beta. The C matrix likely contained
  non-numeric values such as NaN, which then would have resulted in a
  false failure.
- Fixed a bug whereby the implementation for bli_herk_determine_kc(),
  in bli_l3_blocksize.c, was inadvertantly being defined in terms of
  helper functions meant for trmm. This bug was probably harmless since
  the trmm code should have also done the right thing for herk.
- Used cpp macros to neutralize the various AOCL_DTL_TRACE_ macros in
  kernels/zen/3/bli_gemm_small.c since those macros are not used in
  vanilla BLIS.
- Added cpp guard to definition of bli_mem_clear() in bli_mem.h to
  accommodate C++'s stricter type checking.
- Added cpp guard to test/*.c drivers that facilitate compilation on
  Windows systems.
- Various whitespace changes.
