The AVX2 version supports fewer element types than the AVX512 version and may fail at runtime if unsupported types are encountered. This capability information should be exposed to the JVMCI compiler to properly guard against incorrect intrinsification. This is especially important because VM_Version::supports_avx512_simd_sort includes a special exclusion rule for AMD Zen4, due to performance considerations.
