	(sh_cc_enum): New static string array.
	(sh_active_calling_convention): New static string pointer denoting
	active user chosen ABI.
	(sh_is_renesas_calling_convention): New function to return function
	specific ABI, or user choice if necessary.
	(sh_use_struct_convention): Rename first argument and turn around its
	meaning.  Check for renesas ABI and return accordingly.
	(sh_use_struct_convention_nofpu): New function.
	(sh_next_flt_argreg): Get function type as third parameter.  Check
	for renesas ABI and choose floating registers accordingly.
