Subject: Initial infrastructure and hello world for the Scala.js back-end.

The Scala.js back-end can be enabled with the `-scalajs`
command-line option. Currently, it adds one phase to the pipeline,
which emits .sjsir files from trees.

A sandbox project `sjsSandbox`, in `sandbox/scalajs/`, can be used
to easily test Scala.js compilation. One can run the `main()`
method of the `hello.world` object with

  > sjsSandbox/run

The back-end only contains the bare mimimum to compile the hello
world application in the sandbox. Anything else will blow up
(for example, primitive method calls). It is a work-in-progress.
