	* par-ch6.adb: Fix error in handling of parametrized expressions.
	* par-ch4.adb (P_Name): Allow qualified expression as name in Ada 2012
	mode.
	(P_Simple_Expression): Better message for qualified expression prefix
	* s-crc32.adb: Minor reformatting.
	* exp_intr.adb (Expand_Unc_Deallocation): Remove test for empty
	storage pool (this test is moved to Sem_Intr).
	* sem_intr.adb (Check_Intrinsic_Call): Add check for deallocation from
	empty storage pool, moved here from Exp_Intr and made into error.
	(Check_Intrinsic_Call): Remove assumption in generating not-null free
	warning that the name of the instantiation is Free.
	* sinput.adb (Tree_Read): Document use of illegal free call allowed in
	GNAT mode.
	* types.ads: Remove storage size clauses from big types (since we may
	need to do deallocations, which are now illegal for empty pools).
