sparc.c (scan_record_type): Handle vector types.

	* config/sparc/sparc.c (scan_record_type): Handle vector types.
	(function_arg_slotno): Handle vector types specially.
	(function_arg_record_value_1): Split fields with vector type and
	BLKmode into their subparts.
	(function_arg_record_value_2): Likewise.  Be prepared to handle
	more than 2 registers per field.
	(function_arg_union_value): Increment regno inside the loop.
	(function_arg_vector_value): New function.
	(function_arg): Use it to split fields with vector type and
	BLKmode into their subparts and build a PARALLEL.  Treat
	other vector types like floats.
	(function_value): Likewise.
	(sparc_pass_by_reference): Handle vector types.
	(sparc_return_in_memory): Likewise.
