Detailed Description

AES-NI transformations of one 16-byte state in little-endian register order. Bytes 4 * column + row form the AES state matrix. Encryption and decryption rounds add the key last, unlike ARM AESE/AESD. AESDEC uses inverse-mixed intermediate round keys; AESDECLAST uses the original initial key. Each runtime operation requires AES; the SIMD storage requires SSE2. Arch records requirements; the caller must separately enable and admit its target. These integer operations do not modify floating-point status. Constant evaluation computes the same values. Feature-absent tags are accepted only at compile time and still require complete SIMD storage.

Substitute the odd words and return their substituted and rotated forms with the round constant. Imm8 is an unsigned byte in [0,255], XORed into the rotated words.
