Chen, Guobing	deaeb6c5b8	Add bfloat16 based dot and conversion with single/double 1. Added bfloat16 based dot as new API: shdot 2. Implemented generic kernel and cooperlake-specific (AVX512-BF16) kernel for shdot 3. Added 4 conversion APIs for bfloat16 data type <=> single/double: shstobf16 shdtobf16 sbf16tos dbf16tod shstobf16 -- convert single float array to bfloat16 array shdtobf16 -- convert double float array to bfloat16 array sbf16tos -- convert bfloat16 array to single float array dbf16tod -- convert bfloat16 array to double float array 4. Implemented generic kernels for all 4 conversion APIs, and cooperlake-specific kernel for shstobf16 and shdtobf16 5. Update level1 thread facilitate functions and macros to support multi-threading for these new APIs 6. Fix Cooperlake platform detection/specify issue when under dynamic-arch building 7.

Add bfloat16 based dot and conversion with single/double

1. Added bfloat16 based dot as new API: shdot
2. Implemented generic kernel and cooperlake-specific (AVX512-BF16) kernel for shdot
3. Added 4 conversion APIs for bfloat16 data type <=> single/double: shstobf16 shdtobf16 sbf16tos dbf16tod
     shstobf16 -- convert single float array to bfloat16 array
     shdtobf16 -- convert double float array to bfloat16 array
     sbf16tos  -- convert bfloat16 array to single float array
     dbf16tod  -- convert bfloat16 array to double float array
4. Implemented generic kernels for all 4 conversion APIs, and cooperlake-specific kernel for shstobf16 and shdtobf16
5. Update level1 thread facilitate functions and macros to support multi-threading for these new APIs
6. Fix Cooperlake platform detection/specify issue when under dynamic-arch building
7. Change the typedef of bfloat16 from unsigned short to more strict uint16_t
