	(init_cumulative_args, output_mi_thunk): Check for both
	longcall and shortcall attributes on the function.
	(rs6000_attribute_table): Add "shortcall".

	(altivec_expand_unop_builtin, altivec_expand_binop_builtin,
	altivec_expand_ternop_builtin): Add default clauses to switches
	to silence warnings.
	
	* config/rs6000/rs6000.h: Declare rs6000_longcall_switch and
	rs6000_default_long_calls.  Define REGISTER_TARGET_PRAGMAS.
