[PATCH v2 2/2] Add bfloat16 support for AVX512 register view.

This adds support for the bfloat16 datatype, which can be seen as a short version of FP32, skipping the least significant 16 bits of the mantissa. Since the datatype is currently only supported by the AVX512 registers, the printing of bfloat16 values is only supported for xmm, ymm and zmm registers
