          * sh.h (OLD_ARG_MODE): New macro.
          (FUNCTION_ARG_ADVANCE, FUNCTION_ARG_PASS_BY_REFERENCE): Use it.
          (FUNCTION_ARG_1): Break out of:
          (FUNCTION_ARG).  Use OLD_ARG_MODE.

          * sh.h (FUNCTION_ARG_1): Consistently use NEW_MODE for the mode
          of the generated register.

	* sh.h (FUNCTION_ARG_SCmode_WART): Define.
	(FUNCTION_ARG): Unless FUNCTION_ARG_SCmode_WART is defined and
	an even number of floating point regs are in use, use the same
	sequence of argument passing registers for SCmode as would be
	used for two SFmode values.
	* sh.c (sh_va_arg): If FUNCTION_ARG_SCmode_WART is defined,
	swap real / imaginary parts in incoming SCmode values passed
	in registers.
