cleanup: use value_lazy_at instead of allocate_value_lazy/attribute setter

Browse Source 
I came across a pattern used to construct a value in the following way:

  struct value *val = allocate_value_lazy (type);
  VALUE_LVAL (val) = lval_memory;
  set_value_address (val, address);

Instead we fold the above call into:

  value_at_lazy (type, addr);

	* dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Use value_at_lazy instead
	of assembling value via allocate_value_lazy and attribute setter.
	* findvar.c (default_read_var_value): Use value_at_lazy instead of
	assembling value via allocate_value_lazy and attribute setter.
	* valops.c (do_search_struct_field): Use value_at_lazy instead of
	assembling value via allocate_value_lazy and attribute setter.
