--- Comment #5 from Andrew V. Tischenko <andrew.v.tischenko at gmail.com> ---
I was wrong: I used wrong tests. Now I see that everything is OK:

        movw    %bx, %cs:(%rsi,%rbp)    # encoding: [0x2e,0x66,0x89,0x1c,0x2e]
        movl    %ebx, %cs:(%esi,%ebp)   # encoding: [0x2e,0x67,0x89,0x1c,0x2e]
        movl    %ebx, %cs:(%rsi,%rbp)   # encoding: [0x2e,0x89,0x1c,0x2e]
        movw    %bx, %cs:(%esi,%ebp)    # encoding:
[0x2e,0x67,0x66,0x89,0x1c,0x2e]
        movw    %bx, %cs:(%esi,%ebp)    # encoding:
[0x2e,0x67,0x66,0x89,0x1c,0x2e]

and it work for both 32 and 64 bits:

        movw    %bx, %cs:(%esi,%ebp)    # encoding: [0x2e,0x66,0x89,0x1c,0x2e]
        movl    %ebx, %cs:(%si)         # encoding: [0x2e,0x67,0x89,0x1c]
        movl    %ebx, %cs:(%esi,%ebp)   # encoding: [0x2e,0x89,0x1c,0x2e]
        movw    %bx, %cs:(%si)          # encoding: [0x2e,0x67,0x66,0x89,0x1c]
        movw    %bx, %cs:(%si)          # encoding: [0x2e,0x67,0x66,0x89,0x1c]

Because of that I'm closing the bug again. Sorry for boring you.
