	* calls.c (struct arg_data): Move offset, slot_offset, size and
	alignment_pad to struct locate_and_pad_arg_data.  Update all refs.
	(initialize_argument_information): Adjust call to locate_and_pad_parm.
	Delete alignment_pad var.  Don't calculate slot_offset here.
	(emit_library_call_value_1): Delete alignment_pad, offset and size
	vars.  Use struct locate_and_pad_arg_data instead.  Adjust refs.
	Adjust call to locate_and_pad_parm.  Don't tweak arg size for
	partial in-regs here.  Formatting fixes.
	* expr.h (struct locate_and_pad_arg_data): New struct.
	(locate_and_pad_parm): Adjust declaration.
	* function.c (assign_parms): Localize vars.  Use "locate" instead of
	other arg location vars.  Don't invoke FUNCTION_ARG or
	FUNCTION_INCOMING_ARG unless pretend_named is different from
	named_arg.  Heed MUST_PASS_IN_STACK and set up "partial" before
	calling locate_and_pad_parm.  Adjust locate_and_pad_parm call.
	Use slot_offset for stack home of reg parms.  Correct test for
	parm passed in memory.  Formatting fixes.
	(locate_and_pad_parm): Add "partial" to params.  Replace offset_ptr
	arg_size_ptr and alignment pad with "locate".  Set slot_offset here.
	Correct initial_offset_ptr handling.  Localize vars.  Always pad
	locate->offset even when in_regs.
