	* sem_aggr.adb (Resolve_Array_Aggregate): If the expression in an
	others choice is a literal analyze it now to enable later optimizations.
	* exp_aggr.adb (Expand_Record_Aggregate): An aggregate with static size
	and components can be handled by the backend even if it is of a limited
	type.

	* a-rttiev.adb (task Timer): Since this package may be elaborated
	before System.Interrupt, we need to call Setup_Interrupt_Mask
	explicitly to ensure that this task has the proper signal mask.

	* freeze.adb (Freeze_Entity): For array case, move some processing for
	pragma Pack, Component_Size clause and atomic/volatile components here
	instead of trying to do the job in Sem_Ch13 and Freeze.
	* layout.adb: Use new Addressable function
	* sem_ch13.adb (Analyze_Attribute_Representation_Clause, case
	Component_Size): Move some handling to freeze point in
	Freeze.Freeze_Entity.
	* sem_prag.adb (Analyze_pragma, case Pack): Move some handling to
	freeze point in Freese.Freeze_Entity.
	* sem_util.ads, sem_util.adb (Addressable): New function.
