* Bug Fixes in LPGEMM for AVX512(SkyLake) machine
- B-matrix in bf16bf16f32obf16/f32 API is re-ordered. For machines that
doesn't support BF16 instructions, the BF16 input is unre-ordered and
converted to FP32 to use FP32 kernels.
- For n = 1 and k = 1 sized matrices, re-ordering in BF16 is copying the
matrix to the re-ordered buffer array. But the un-reordering to FP32
requires the matrix to have size multiple of 16 along n and multiple
of 2 along k dimension.
- The entry condition to the above has been modified for AVX512 configuration.
- In bf16 API, the tiny path entry check has been modified to prevent
seg fault while AOCL_ENABLE_INSTRUCTIONS=AVX2 is set in BF16 supporting
machines.
- Modified existing store instructions in FP32 AVX512 kernels to support
execution in machines that has AVX512 support but not BF16/VNNI(SkyLake).
- Added Bf16 beta and store types in FP32 avx512_256 kernels

* Bug Fixes in LPGEMM for AVX512(SkyLake) machine
- Support added in FP32 512_256 kerenls for : Beta, BIAS, Zero-point and
BF16 store types for bf16bf16f32obf16 API execution in AVX2 mode.

- Fix for seg fault with AOCL_ENABLE_INSTRUCTIONS=AVX2 mode in BF16/VNNI
ISA supporting configruations:
- BF16 tiny path entry check has been modified to take into account arch_id
to ensure improper entry into the tiny kernel.
- The store in BF16->FP32 col-major for m = 1 conditions were updated to
correct storage pattern,
- BF16 beta load macro was modified to account for data in unaligned memory.
- Modified existing store instructions in FP32 AVX512 kernels to support
execution in machines that has AVX512 support but not BF16/VNNI(SkyLake)
