It is time to give some attention to the
ARM_NEONback-end, which has fallen behind quite a bit.This PR corresponds to PRs #531, #533, #534 and applies the on-the-fly repacking technique to
Q4_0, Q4_1, Q5_0, Q5_1, Q6_0, Q8_0, IQ4_NLfor theARM_NEONimplementation.Here is a PP-512 performance comparison between the main branch and this PR for LlaMA-3.1-8B-Instruct on M2-Max
