    [CGP] Fix Complex addressing mode for offset

    If the offset is differ in two addressing mode we can continue only
    if ScaleReg is not set due to we will use it as merge of different
    offsets.

    It should fix PR35799 and PR35805.

  graphics/xpx, mail/alpine and editors/pico-alpine ports.
