commit aa7524da75c21a71668a67308085706d020fdfb0

    Use input type in coder inference for MapElements and FlatMapElements
    Previously, the input TypeDescriptor was unknown, so we would fail
    to infer a coder for things like MapElements.of(SimpleFunction<T, T>)
    even if the input PCollection provided a coder for T.
    Now, the input type is plumbed appropriately and the coder is inferred.
