can we move this guy up in CompilationJob?

[bradn, 2017/03/22 18:46:45]

Ugh.
If you mean CompilationJob, that's tricky as it's meant to be opaque.
That seems like it would muddy up things elsewhere.
An alternative would be a common base for PipelineCompilationJob /
WasmCompilationJob that adds in pipeline_stat + zone_stats?

Do you mean move it into PipelineData?
That might be cleaner, but wow that guy is a rather odd how it seems to only
hold references, yick.

   PipelineData data_;
   PipelineImpl pipeline_;
   Linkage linkage_;
