	* exp_ch4.adb (Wrap_MA): New function.
	(Expand_N_Op_Expon): Use Wrap_MA.

	* exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration):
	Do not use secondary stack to return limited records with
	defaulted discriminants. This is an efficiency improvement.
	* exp_ch6.adb, exp_dist.adb, sem_attr.adb, sem_aux.adb, sem_aux.ads,
	sem_ch12.adb, sem_ch3.adb, sem_ch4.adb, sem_ch6.adb, sem_ch7.adb,
	sem_util.adb: Change the sense of Is_Indefinite_Subtype to be
	Is_Definite_Subtype. This is an improvement to readability (the double
	negative in "not Is_Indefinite_Subtype" was slightly confusing). Also
	disallow passing non-[sub]type entities, an unnecessary and slightly
	bug-prone flexibility.
