	* exp_ch5.adb (Expand_Iterator_Loop_Over_Array): Use the SLOC of the
	iteration scheme throughout, except for the new loop statement(s).

	* exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
	assignment if it is part of an Iterated_Component_Association: the
	analysis needs to take place once the loop structure is analyzed and
	the loop parameter made visible, because references to it typically
	appear in the corresponding expression.  This is necessary if the
	expression is an aggregate, because previous pre-analysis of the
	expression does not handle nested aggregates properly.

	* sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
	allocator that is the expansion of a build-in-place function call.

	* s-trasym__dwarf.adb (spec of Module_Name.Get): Instead of
	possibly adjusting the lookup address by a load address, expect
	a extra argument through which the load address can be conveyed
	separately.
	(Multi_Module_Symbolic_Traceback): Adjust accordingly. Pass the
	retrieved load address to Init_Module.
	* s-tsmona__linux.adb (Get): Honor the new interface.
	* s-tsmona__mingw.adb (Get): Likewise.
	* s-dwalin.ads: Adjust comments to be explicit about which
	addresses are from module info and which are run-time addresses,
	offsetted by the module load address.
	* s-dwalin.adb (Set_Load_Address): Simply set C.Load_Slide.
	Do not alter the module Low and High (relative) addresses.
	(Is_Inside): Improve documentation regarding the kinds of addresses
	at hand and correct the test.
	(Symbolic_Traceback): Use separate variables with explicit names
	for the address in traceback (run-time value) and the address to
	lookup within the shared object (module-relative). Adjust the
	computation of address passed to Symbolic_Address for symbolization.
