[swift-corelibs-dev] NSOperationQueue and friends

[Daniel Eggert]

This is on OS X will everything pulled from master yesterday. I'm using Xcode, and I built a toolchain from source. Same happens with the 2016-03-24 toolchain from swift.org.

For some reason DEPLOYMENT_ENABLE_LIBDISPATCH isn't set, but I guess it should be?

It is worth noting that this implementaiton has a few behavioral differences between this implementation and the one implemented in objective-c. Part of this difference is due to features like QoS not being cross platform portable or KVO not yet implementable in Swift. This is very much a work-in-progress; it needs unit tests and and a bit more polish, but hopefully it is good enough to get some work started in some other places.
