https://dart-review.googlesource.com/c/sdk/+/498840 added support for promotion of properties (private, final instance variables with a name which isn't used much for other purposes) in the context of anonymous methods. This CL reduces the set of situations where this feature is enabled such that only `this` will allow property promotions to be carried in (such that `this._x` is promoted in `v.=> this._x` when `v` is such that `v._x` has been promoted before the anonymous method occurs). It also generalizes the mechanism such that property promotions are carried out (so we can do `if (v.=> _x is int) v._x.isEven;`). Tests has been adjusted accordingly.
