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.
