	* sem_ch3.adb (Constrain_Corresponding_Record): For the case
	of the subtype created for a record component, do not mark
	the subtype as frozen. For one thing, this is anomalous (in
	particular, the base type might not itself be frozen yet);
	furthermore, proper freezing of the subtype must happen in any
	case. So, we just mark the subtype as requiring delayed freezing
	(and we'll actually freeze it when generating the init_proc of
	the enclosing record).
	Also change the name of the constrained record subtype (append a
	'C' so that it is clearly different from the unconstrained record
	type, "related_idV") to make debugging easier.
	(Process_Full_View): When creating a full subtype for a pending
	private subtype, re-establish the scope of the private subtype
	so that we get proper visibility on outer discriminants.
	* exp_ch3.adb (Build_Init_Statements): Freeze any component
	subtype that is not frozen yet.
