[PATCH] D58572: [Support] allow -stats/-time-passes reporting into a custom stream

[Philip Pfaffe via Phabricator via llvm-commits]

I don't think this is sufficient or goes into the right direction to support parallel info collection and output.

For the new PassManager, reporting per-thread timings is trivial already and requires no (additional) global state. You can just create a TimePassesHandler instance per thread or per pipeline.
For Statistics on the other hand the approach in this change is insufficient, because the statistics registry is already a singleton. In order to support parallel statistics collection, can we get rid of the Statistics singleton?
