This spewer design has two goals:
1. Provide a spew mechanism that has first-class support for slicing and
dicing output. This means that filtering by script and channel should be
the dominant output mechanism.
2. Provide a simple powerful mechanism for getting information out of the
compiler and into tools. I'm inspired by tools like CacheIR analyzer,
IR Hydra, and the upcoming tracelogger integration into perf.html.
