	predicate compatible with Ada 2012 definition

	record type with a limited component.

	sem_util.adb, sem_res.adb, sem_prag.adb, sem_attr.adb, sem_ch8.adb,
	sem_ch6.adb, sem_ch3.adb, exp_util.adb: Use Is_Limited_View
	* freeze.adb Use Is_Immutably_Limited_Type to check the legality
	of references to the current instance, Is_Limited_View otherwise.
