    i386: Don't add 0x66 prefix to IRET for .code16gcc

    The .code16gcc directive supports 16bit mode with 32-bit address.  Since
    IRET (opcode 0xcf) in 16bit mode returns from an interrupt in 16bit mode,
    we shouldn't add 0x66 prefix for IRET.

        PR gas/24485
        * config/tc-i386.c (process_suffix): Don't add DATA_PREFIX_OPCODE
        to IRET for .code16gcc.
        * testsuite/gas/i386/jump16.s: Add IRET tests.
        * testsuite/gas/i386/jump16.d: Updated.
