When detecting illegal uses of formal parameters of the current
subprogram in contract of its Exceptional_Cases, we relied on the
Current_Scope. However, quantified expressions introduce an implicit
scope, which we need to take into account.

gcc/ada/

	* sem_res.adb (Resolve_Entity_Name): Ignore implicit loop scopes
	introduced by quantified expressions.

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