    x86: Update register operand check for AddrPrefixOpReg

    When the address size prefix applies to both the memory and the register
    operand, we need to extract the address size prefix from the register
    operand if the memory operand has no real registers, like symbol, DISP
    or symbol(%rip).

    NB: GCC always generates symbol(%rip) for RIP-relative addressing for
    both x32 and x86-64.

    Move the .code16 tests in movdir.s to movdir-16bit to show the correct
    output from objdump.

            * config/tc-i386.c (process_suffix): Also check the register
            operand for the address size prefix if the memory operand has
            no real registers.
