This patch upstreams llamafile's cpu matrix multiplication kernels for ppc64le using MMA builtins for BF16 data type. This change results in 9x - 40x gains in total speed S t/s (ie all tokens/total time), across various batch sizes tested using llama-batched-bench benchmark. The patch is tested with Meta-Lllama-3-8B, and Mistral-7B models (BF16 models generated by using llama-quantize from corresponding FP32 models) on an IBM POWER10 machine.
