	* exp_ch4.adb (Expand_N_Type_Conversion): Perform Integer promotion for
	the operand of the unary minus and ABS operators.

	* sem_type.adb (Covers): A concurrent type and its corresponding record
	type are compatible.
	* exp_attr.adb (Expand_N_Attribute_Reference): Do not rewrite a 'Access
	attribute reference for the current instance of a protected type while
	analyzing an access discriminant constraint in a component definition.
	Such a reference is handled in the corresponding record's init proc,
	while initializing the constrained component.
	* exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
	corresponding record type, propagate components'
	Has_Per_Object_Constraint flag.
	* exp_ch3.adb (Build_Init_Procedure.Build_Init_Statements):
	For a concurrent type, set up concurrent aspects before initializing
	components with a per object constrain, because they may be controlled,
	and their initialization may call entries or protected subprograms of
	the enclosing concurrent object.
