ggml : x2 speed for WASM by optimizing SIMD (llama/11453)
* ggml : x2 speed for WASM by optimizing SIMD * fix bad merging * rm trailing spaces * rm redundant clamp * better quantize_row_q8_K Co-authored-by: camel-cdr <camel-cdr@protonmail.com> * remove memset that causes buffer overflow Co-authored-by: camel-cdr <camel-cdr@protonmail.com> --------- Co-authored-by: camel-cdr <camel-cdr@protonmail.com>
