Fix CompilationStateBuilder's speed tracer logs.

Currently, CompilationStateBuilder produces a tree like:

Process
- Process

Where the top node has almost no time in it at all, and serves no purpose.  This
jiggles things so you get a trace more like:

Process
- JdtCompile
- Process (many, smaller ones)
