New instructions are added to AArch32 and AArch64 to aid floating-point multiplication and addition of complex numbers, where the complex numbers are packed in a vector register as a
pair of elements. The Imaginary part of the number is placed in the more significant element, and the Real part of the number is placed in the less significant element.
