Code cleanup making also optimized out values lazy.
	* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Use
	allocate_optimized_out_value.  Twice.
	(loclist_read_variable)  Use allocate_optimized_out_value.  Once.
	* findvar.c (read_var_value): Likewise.
	* value.c (allocate_optimized_out_value): New function.
	* value.h (allocate_optimized_out_value): New declaration.
