    Message : Expose the IntermNode tree generated in the compiler for testing This refactoring makes it possible for tests to access the IntermNode tree produced by compilation by calling compileTree(). Removing ParseContext usage from OutputHLSL has the additional benefit of better separation between parsing and output.
