Hongtao Liu 4f0e90fae9 Enable support for bfloat16 which will be in Future Cooper Lake. 
There are 3 instructions for AVX512BF16: VCVTNE2PS2BF16, VCVTNEPS2BF16 and
DPBF16PS instructions, which are Vector Neural Network Instructions
supporting:
    
- VCVTNE2PS2BF16: Convert Two Packed Single Data to One Packed BF16 Data.
- VCVTNEPS2BF16: Convert Packed Single Data to Packed BF16 Data.
- VDPBF16PS: Dot Product of BF16 Pairs Accumulated into Packed Single Precision.
