Summary: Metro symbolication can be expensive in large apps. However, there is no need to symbolicate _runtime stacks from compile errors_. Those are pretty much useless anyway. This will reduce the workload on Metro workers, and the delays when iterating with Fast Refresh, as the server will be busy much less often. So I'm special-casing them and not sending the symbolication request anymore. Reviewed By: rickhanlonii Differential Revision: D16030087 fbshipit-source-id: 41f83ac01780c0a60cca777014e4ed95c0f3d14b
