Do we need this for setters as well?

Doesn't synthetic getter imply synthetic setter? Actually, now that I think
about it, when we fix https://github.com/dart-lang/dev_compiler/issues/497 it
might be possible to have synthetic getters and implemented setters (the
synthetic getter is just a call to the super getter).

       // Tear-off methods: explicitly bind it.
