	* exp_ch5.adb (Expand_N_Extended_Return_Statement): Suppress generation
	of a heap allocator for a limited unconstrained function return when
	resstriction No_Allocators is active.
	(Analyze_Allocator): The restriction No_Allocators is now only checked
	on allocators that have Comes_From_Source set, as per RM-H.4(7).

	* sem_ch4.adb (Expand_N_Extended_Return_Statement): Suppress generation
	of a heap allocator for a limited unconstrained function return when
	resstriction No_Allocators is active.
	(Analyze_Allocator): The restriction No_Allocators is now only checked
	on allocators that have Comes_From_Source set, as per RM-H.4(7).
	(Has_Fixed_Op):  If the name in a function call is Standard."*" and the
	operands are fixed-point types, the universal_fixed predefined operation
	is used, regardless of whether the operand type (s) have a primitive
	operation of the same name.
