Rollup merge of rust-lang#140389 - sayantn:avx512fp16, r=Amanieu Remove `avx512dq` and `avx512vl` implication for `avx512fp16` According to Intel, `avx512fp16` requires only `avx512bw`, but LLVM also enables `avx512vl` and `avx512dq` when `avx512fp16` is active. This is relic code, and will be fixed in LLVM soon. We should remove this from Rust too asap, especially before the stabilization of AVX512 Related: - llvm/llvm-project#136209 - rust-lang#138940 - rust-lang/stdarch#1781 - rust-lang#111137 ``@rustbot`` label O-x86_64 O-x86_32 A-SIMD A-target-feature T-compiler -T-libs r? ``@Amanieu`` **Update: the LLVM fix has been merged** cc ``@rust-lang/wg-llvm`` will it be possible to update the rustc llvm version to something after llvm/llvm-project#137450
