John Brawn 49e61d90ca [AArch64] Do 64-bit vector move of 0 and -1 by extracting from the 128-bit move
Currently a vector move of 0 or -1 will use different instructions depending on
the size of the vector. Using a single instruction (the 128-bit one) for both
gives more opportunity for Machine CSE to eliminate instructions.
