This is basically an issue to make NativeAOT pass the test CompilerGeneratedCodeInPreservedAssembly

The scenario is an assembly which is entirely preserved via a descriptor XML and it contains unreachable code in constant condition branch which is compiler generated and triggers a data flow warning. This should not produce a warning, but it still does.

		public static void WithLocalFunction ()
		{
			if (AlwaysFalse) {
				LocalWithWarning ();
			}

			[ExpectedWarning ("IL2026", ProducedBy = Tool.Analyzer | Tool.NativeAot)] // Bug
			void LocalWithWarning ()
			{
				Requires ();
			}
		}
