Log message:
	* except.c (EH_RETURN_STACKADJ_RTX): Do not define.
	(EH_RETURN_HANDLER_RTX): Likewise.
	(expand_builtin_eh_return): Do not copy stack adjustment
	if EH_RETURN_STACKADJ_RTX is not defined.
	(expand_eh_return): Likewise.  Also, do not pass stack
	adjustment as argument to the eh_return pattern.
	* except.h (MUST_USE_SJLJ_EXCEPTIONS): Do not define just
	because EH_RETURN_STACKADJ_RTX is not defined.
	* unwind-dw.c (uw_update_context_1): If EH_RETURN_STACKADJ_RTX
	is not defined, treat stack pointer like a regular register.
	(uw_init_context_1): Set up fake initial stack pointer register.
	(uw_install_context_1): Do not compute stack adjustment if
	EH_RETURN_STACKADJ_RTX is not defined.
	
	* config/i386/i386.md ("eh_return"): Remove first argument.
	* config/mips/mips.md ("eh_return"): Likewise.
	* config/rs6000/rs6000.md ("eh_return"): Likewise.
	* config/sh/sh.md ("eh_return"): Likewise.
	
	* config/s390/s390.h (EH_RETURN_STACKADJ_RTX): Remove.
