[PATCH v1 1/1] x86: Enable Prefer_No_AVX512 for Hygon model 0x8

[Jiamei Xie]

From: xiejiamei <xiejiamei@hygon.cn>

Extend the Prefer_No_AVX512 tuning to cover Hygon model 0x8.

Benchmarks on Hygon platforms show that EVEX implementations
are often more profitable than AVX512 paths. The existing logic
already enables Prefer_No_AVX512 for model 0x7. Apply the same
preference to model 0x8 to ensure consistent IFUNC selection
behavior across newer Hygon processors.
