It makes no sense whatsoever to do this at each function call; we already have a table for this.

This fixes a data race warning by ThreadSanitizer. FrameThreadContext.die is read by all the worker threads but is not protected by any mutex. Move it to PerThreadContext so that each worker thread reads its own copy of |die|, which can then be protected with PerThreadContext.mutex. Signed-off-by:
