Options

sh.h (current_function_anonymous_args): Remove. 

	* sh.h (current_function_anonymous_args): Remove.
	(SETUP_INCOMING_VARARGS): Don't set it - just check that one
	of current_function_varargs and current_function_stdarg is set.
	* sh.c (sh_expand_prologue): Check current_function_varargs /
	current_function_stdarg / TARGET_SH5 instead of
	current_function_anonymous_args.

	* sh64.h (TARGET_VERSION): Define.

Fix comments that to refer to SH architecture -
the architecture is no longer exclusive to Hitachi.
