When encountering call this.m(...) we can check if m resolves to the same
method in all concrete subclasses of the receiver class. If it does then
we don't need any checks and can just use a StaticCall instead of InstanceCall.
This is allows us to improve code quality for cases like:
class Base {
var _field;
foo() { _field = true; }
}
class A01 extends Base { }
...
class A16 extends Base { }
Previously AOT would generate InstanceCall(get:_field) in the method foo.
However with this change we generate StaticCall(...) which subsequently gets
handled by the inliner.
