	* sem_prag.ads (Process_Compile_Time_Warning_Or_Error): New

	of the regular processing of these pragmas and as part of its
	validation after invoking the backend.
	* sem_prag.adb (Process_Compile_Time_Warning_Or_Error): New
	subprogram.
	(Process_Compile_Time_Warning_Or_Error): If the
	condition is known at compile time then invoke the new overloaded
	subprogram; otherwise register the pragma in a table to validate
	it after invoking the backend.
	* sem.ads, sem.adb (Unlock): New subprogram.
	* sem_attr.adb (Analyze_Attribute [Size]): If we are processing
	pragmas Compile_Time_Warning and Compile_Time_Errors after the
	backend has been called then evaluate this attribute if 'Size
	is known at compile time.
	* gnat1drv.adb (Post_Compilation_Validation_Checks): Validate
	compile time warnings and errors.
