    aarch64: Treat operand "SME list of ZA tiles" as immediate (PR 31561)

    The AArch64 instruction table (aarch64-tbl.h) defines the operand
    "SME list of ZA tiles" (SME_list_of_64bit_tiles) as immediate. During
    assembly it is correctly encoded as immediate value (imm.value) in
    parse_operands. During disassembly it is first correctly decoded as
    immediate value (imm.value) in aarch64_ext_imm called by
    aarch64_extract_operand, but then erroneously treated as register
    number (reg.regno) in aarch64_print_operand.

    This resolves the assembler test case "SME extension (ZERO)" to
    erroneously fail on s390. On AArch64 - being little-endian - the struct
    aarch64_opnd_info union fields reg.regno and imm.value share their
    least-significant bits. On s390 - being big-endian - they do not.
