Detailed Description

Individual Advanced SIMD operations on four native-order uint32_t words. Runtime calls require the named instruction feature; the compiler's "sm4" target enables both SM3 and SM4. Admit target_features<arm>("sm4") before entering its compiled leaf. These operations do not modify FPCR, FPSR or NZCV. Feature-absent overloads are immediate-only and require NEON vector storage.
