	* exp_aggr.adb (Expand_Array_Aggregate): If the aggregate contains
	tasks, create an activation chain now, before the expansion into
	assignments and build-in-place calls that require the presence of an
	activation chain.
	(Backend_Processing_Possible): If the component type is inherently
	limited, the aggregate must be expanded into individual built-in-place
	assignments.

	* sem_ch6.adb (Build_Extra_Formals): Use underlying type of result to
	determine whether an allocation extra parameter must be built, to
	handle case of a private type whose full type is a discriminated type
	with defaults.
