Exclusive-OR and Rotate performs a bitwise exclusive-OR of the 128-bit vectors in the two source SIMD&FP registers, rotates each 64-bit element of the resulting 128-bit vector right by the value specified by a 6-bit immediate value, and writes the result to the destination SIMD&FP register.
This instruction is implemented only when FEAT_SHA3 is implemented.
