AstDumper (GWT DEV 2.7.0)

```
public class AstDumper
extends Object
```
A simple utility to dump a JProgram to a temp file, which can be called sequentially during a compilation/optimization run, so intermediate steps can be compared. It uses the system property "gwt.jjs.dumpAst" to determine the name (or prefix) of the file to dump the AST to. TODO(jbrosenberg): Add proper logging and/or exception handling for the potential IOException that might occur when writing the file.
