The problem is that the APX encoding length for AND exceeds 15 bytes with
-mx32.

    x86: Allow TImode offsettable memory only with 8-bit constant

    The x86 instruction size limit is 15 bytes.  If a NDD instruction has
    a segment prefix byte, a 4-byte opcode prefix, a MODRM byte, a SIB byte,
    a 4-byte displacement and a 4-byte immediate, adding an address size
    prefix will exceed the size limit.  Change TImode ADD, AND, OR and XOR
    to allow offsettable memory only with 8-bit signed integer constant,
    which is encoded with a 1-byte immediate, if the address size prefix
    is used.
