3d74b62e60 Lpgemm threading and micro-kernel optimizations.
-Certain sections of the f32 avx512 micro-kernel were observed to
slow down when more post-ops are added. Analysis of the binary
pointed to false dependencies in instructions being introduced in
the presence of the extra post-ops. Addition of vzeroupper at the
beginning of ir loop in f32 micro-kernel fixes this issue.
-F32 gemm (lpgemm) thread factorization tuning for zen4/zen3 added.
-Alpha scaling (multiply instruction) by default was resulting in
performance regression when k dimension is small and alpha=1 in s32
micro-kernels. Alpha scaling is now only done when alpha != 1.
-s16 micro-kernel performance was observed to be regressing when
compiled with gcc for zen3 and older architecture supporting avx2.
This issue is not observed when compiling using gcc with avx512
support enabled. The root cause was identified to be the -fgcse
optimization flag in O2 when applied with avx2 support. This flag is
now disabled for zen3 and older zen configs.

8dff49837d Lpgemm source restructuring to support amdzen config.
-Currently lpgemm can only be built using either zen3 or zen4 config.
The lpgemm kernel code is re-structured to support amdzen, and thus
multi machine deployment.
-The micro-kernel calls (gemm and pack) are currently hardcoded in the
lpgemm framework. This is removed and a new lpgemm_cntx based dispatch
mechanism is designed to support runtime configurability for
micro-kernels.

6fbdfc3cf2 Low precision gemm refactoring and bug fixes.
-The micro-kernel function signatures follow a common pattern. These
functions can be represented as an instantiation of a MACRO as is done
in BLIS, and thus the number of micro-kernel header files can be brought
down. A new single header file containing all the MACRO definitions with
the instantiation is added, and the existing unnecessary header files
are removed.
-The bias addition in micro-kernel for n remaining < 16 reads the bias
array assuming it contains 16 elements. This can result in seg-faults,
since out of bound memory is accessed. It is fixed by copying required
elements to an intermediate buffer and using that buffer for loading.
-Input matrix storage type parameter is added to lpgemm APIs. It can be
either row or column major, denoted by r and c respectively. Currently
only row major input matrices are supported.
-Bug fix in s16 fringe micro-kernel to use correct offset while storing
output.

6c112632a7 Low precision gemm integrated as aocl_gemm addon.
- Multi-Threaded int8 GEMM (Input - uint8_t, int8_t, Output - int32_t).
AVX512_vnni based micro-kernel for int8 gemm. Paralellization supported
along m and n dimensions.
- Multi-Threaded B matrix reorder support for sgemm. Reordering B matrix
is packing entire B matrix upfront before sgemm. It allows sgemm to
take advantage of packed B matrix without incurring packing costs during
runtime.
- Makefile updates to addon make rules to compile avx512 code for
selected files in addon folder.
- CPU features query enhancements to check for AVX512_VNNI flag.
- Bench for int8 gemm and sgemm with B matrix reorder. Supports
performance mode for benchmarking and accuracy mode for testing code
correctness.
