This CL introduces support for anonymous block methods (that is,
`e.{ print(this); }` as opposed to `e.=> print(this);`). It introduces
the notion of a `ReturnContext` which is used to change the semantics
of a return statement when it returns from an anonymous method (where
it works like a `break` that terminates the execution of the block
which is the body of the enclosing anonymous method), but keeps the
semantics of return statements returning from a function (including
function literals) still have the same semantics as today.

This CL changes the code generation for `dart2js` (and not for any other
backend) such that the variable holding the receiver of an anonymous
method invocation is declared as a normal local variable rather than
being a `Let` variable. This is needed because `dart2js` supports
capturing the former, but not the latter.
