This expression transformer is used internally by the trait AST transformation to change the receiver of a message on "this" into a static method call on the trait helper class.

In a nutshell, code like the following method definition in a trait: void foo() { this.bar() } is transformed into: void foo() { TraitHelper$bar(this) }
