function.c (assign_parms): Use all.reg_parm_stack_space instead of re-evaluating REG_PARM_STACK_SPACE... 

2013-11-14  Ulrich Weigand  <Ulrich.Weigand@de.ibm.com>
	    Alan Modra  <amodra@gmail.com>

	* function.c (assign_parms): Use all.reg_parm_stack_space instead
	of re-evaluating REG_PARM_STACK_SPACE target macro.
	(locate_and_pad_parm): New parameter REG_PARM_STACK_SPACE.  Use it
	instead of evaluating target macro REG_PARM_STACK_SPACE every time.
	(assign_parm_find_entry_rtl): Update call.
	* calls.c (initialize_argument_information): Update call.
	(emit_library_call_value_1): Likewise.
	* expr.h (locate_and_pad_parm): Update prototype.
