PPC/s390: Omit check against kDontAdaptArgumentsSentinel

Port aa259e30

Original Commit Message:

    When kDontAdaptArgumentsSentinel is 0 (the receiver is included in the
    argument count), we don't need a dedicated check against the sentinel
    before comparing the formal parameter count to the actual argument count
    when calling a JS function.
