ada: Reject pragma CPU and Priority that duplicate corresponding aspects

When a main subprogram had its CPU or priority specified first by an aspect
specification and then by a corresponding pragma, then the pragma was silently
ignored. Now such a pragma is rejected.

gcc/ada/ChangeLog:

	* sem_ch13.adb (Analyze_Aspect_Specifications): Record aspect CPU and
	Priority applied to subprogram as a representation item.
