	* sem_ch4.adb (Analyze_Indexed_Component_Form): Dimension
	analysis for indexed components added.
	* sem_ch6.adb (Analyze_Function_Call): Dimension propagation
	for function calls added.
	* sem_dim.adb (Analyze_Dimension): Call to
	Analyze_Dimension_Has_Etype when N is a function call.
	(Analyze_Dimension_Call): Don't propagate anymore the dimensions
	for function calls since this is now treated separately in
	Analyze_Dimension_Has_Etype.
	(Analyze_Dimension_Has_Etype): For
	attribute references, propagate the dimensions from the prefix.
	* sem_dim.ads (Copy_Dimensions): Fix comment.

	* checks.ads, checks.adb (Apply_Parameter_Aliasing_Checks): New routine.
	(Apply_Parameter_Aliasing_And_Validity_Checks): This routine
	has been split into two.
	(Apply_Parameter_Validity_Checks): New routine.
	* exp_ch6.adb (Expand_Call): Add checks to verify that actuals
	do not overlap. The checks are made on the caller side to overcome
	issues of parameter passing mechanisms.
	* freeze.adb (Freeze_Entity): Update call to
	Apply_Parameter_Aliasing_And_Validity_Checks.
