[swift-dev] large dictionary literal overflows swiftc stack

I am! Admittedly, that dictionary contains many obsolete mime type mappings which could be pruned (anyone serving Lotus 1-2-3 files?). However, 816 items is not an absurdly large number so it’s likely someone else would have run into this in the near future.

The code does successfully compile for me using the release 2.2 version on my VMWare based Ubuntu 15 system. It also compiles using 3.0.

If there is a problem with swift 3 then I suppose it can be fixed, but if swift 3 has no issues then it looks like I have few options for remediation.
