A field/function annotated with this pragma must be guaranteed to not return `null` at runtime. Make use of this non-nullable annotation in the VM's type propagator. Annotates the "_TypedListView._typedData" field to ensure the VM knows it returns a non-nullable _TypedListView. Furthermore annotates methods on the integer implementation. Those particular methods are recognized methods with a "dynamic" return type. This caused the type propagator to use CompileType::Dynamic() as result type. Since a previous CL started to only utilize the annotated type if it is better than "dynamic" more integer operations got handled in-line, though with null-checks. Annotating those methods to return non-null improves the in-line handling of integer operations. This improves dart-aot On arm7hf: SHA256: +5%, SHA: +6%, JsonObjectRoundTrip: +7%, ...
