685f7089 - ggml-cpu : keep the FP16->FP32 lookup table on x86 with F16C (#30342) (#30343)

ggml-cpu : keep the FP16->FP32 lookup table on x86 with F16C (#30342) (#30343) * ggml-cpu : keep the FP16->FP32 lookup table on x86 with F16C (#30342) #30270 routed both scalar conversions through F16C. For FP16->FP32, Clang 20.1.8 lowers the intrinsic to a vpinsrw merging into the live accumulator register of the quantized dot products, which serialises the loop (19 vs 4 cycles/iteration estimated, 45-65% slower Q8_0/Q4_0 MUL_MAT_ID kernels measured). Keep F16C for FP32->FP16 as intended and the table for FP16->FP32. * ggml-cpu : comment out the F16C FP16->FP32 define instead of removing it (review)
