There's still work left to do. In terms of next steps, there's still rdar://problem/22126141, which covers removing the 'workaround' overloads for print (that prevent bogus overload resolution failures), as well as providing a decent diagnostic when users invoke print with 'appendNewline'.

Now that CGFloat is its own distinct type, it's useful to have Double
initializers to go along with the Int initializers we added a while
back <rdar://problem/17224725>.

The old ones were:
- print/println
- printAny
- printf
- Console
The new printing story is just print/println. Every object can be printed.
You can customize the way it is printed by adopting Printable protocol. Full
details in comments inside stdlib/core/OutputStream.swift.
Printing is not completely finished yet. We still have ReplPrintable, which
should be removed, string interpolation still uses String constructors, and
printing objects that don't conform to Printable will result in printing
mangled names.

Preserve the AbstractCC of a function symbol when emitting a SIL ConstantRefInst by adding a new StaticFunction variant to LoweredValue. This lets us avoid a bunch of bitcasting noise for static functions that aren't used as values, and will lets us emit C-to-Swift-ABI thunks on demand when C functions are used as values.
