We defer some compile time warnings and errors until the
backend has added the extra information needed. However
it is not guaranteed that the backend has run by this point.
Avoid checking these errors if the backend has not been activated
and no code has been generated.

gcc/ada/

	* sem_prag.adb (Validate_Compile_Time_Warning_Errors): Avoid
	checking compile time warnings and errors if backend has not been
	activated.

Tested on x86_64-pc-linux-gnu, committed on master.
