[Bug target/39146] Unnecessary stack alignment

[hjl dot tools at gmail dot com]

This is caused by assign_parms in function.c:

      /* Estimate stack alignment from parameter alignment.  */
      if (SUPPORTS_STACK_ALIGNMENT)
        {
          unsigned int align = FUNCTION_ARG_BOUNDARY (data.promoted_mode,
                                                      data.passed_type);
          if (TYPE_ALIGN (data.nominal_type) > align)
            align = TYPE_ALIGN (data.passed_type);
          if (crtl->stack_alignment_estimated < align)
            {
              gcc_assert (!crtl->stack_realign_processed);
              crtl->stack_alignment_estimated = align;
            }
        }
