IQ4_K_R4 (#138)
* iq4_k_r4: WIP
* iq4_k_r4: Zen4 and hopefully AVX2
On Zen4 we get PP-512(LLaMA-3.1-8B) = 232.6 t/s, up from 182.2 t/s
for iq4_k. Applying the extra shift costs a ~6 performance penalty.
* iq4_k_r4: AVX2
PP-512 = 227.60 t/s. The shifts are really costly.
* iq4_k_r4: NEON
We get PP-512(LLaMA-3.1-8B) = 108 t/s, up from 58.2 t/s for iq4_k.
