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. Change the typedef of bfloat16 from unsigned short to more strict uint16_t

Zaheer Chothia 037d995c4d Fixed noisy warning with Clang 
../common_thread.h:138:24: warning: equality comparison with extraneous parentheses [-Wparentheses-equality]
  if ((blas_cpu_number == 1)
       ~~~~~~~~~~~~~~~~^~~~
../common_thread.h:138:24: note: remove extraneous parentheses around the comparison to silence this warning
  if ((blas_cpu_number == 1)
      ~                ^   ~
../common_thread.h:138:24: note: use '=' to turn this equality comparison into an assignment

Xianyi Zhang ba31b19c00 Ref #62. In OpenMP implementation, check the return value of omp_get_max_threads(). 
It makes sure the return value as same as blas_cpu_numbers which is an internal global variable to store the number of threads in OpenBLAS.
