     AARCH64_FUSION_PAIR (name, internal_name, index_bit)

     NAME is a string giving a friendly name for the instructions to fuse.
     INTERNAL_NAME gives the internal name suitable for appending to
     AARCH64_FUSE_ to give an enum name.
     INDEX_BIT is the bit to set in the bitmask of supported fusion
     operations.  */
