Won't your patch give the following outcome?

  if (GET_CODE (x) == SUBREG || REG_P (x))
    {
      if (GET_CODE (x) == SUBREG
	  && SUBREG_PROMOTED_VAR_P (x)
	  && REG_P (SUBREG_REG (x)))
	record_promoted_value (insn, x);
    }
  else

That's not the same as the original code:

   if (GET_CODE (x) == SUBREG
       && SUBREG_PROMOTED_VAR_P (x)
       && REG_P (SUBREG_REG (x)))
     record_promoted_value (insn, x);
   else
