It will get expanded into MOVPRFX_ZZ and EXT_ZZI by the AArch64ExpandPseudo pass. This instruction takes a single Z register as input, as opposed to the existing destructive EXT_ZZI instruction. Note this patch only defines the pseudo, it isn't used in any ISel pattern yet. It will later be used for vector.extract.
