f456f0c25c Runtime: Enable reflection for multi-payload enums with non-trivial layout
This came up for multi-payload enums without generic parameters, eg

enum MyError {
  case BusError
  case TrainError(Int)
  case DataLoss(String)
}

Fixes <rdar://problem/21739870>.

cdd5a4121c IRGen: Generate value witnesses to get enum tag and project payload
These will be used for reflection, and eventually to speed up generic
operations on single payload enums as well.

Progress on <rdar://problem/21739870>.

d2a5fbd94a Implement reflection on instances of empty and single-payload enums
This change attempts to introduce the functionality without being too
disruptive. After we branch, I want to consolidate some of the runtime
functions and implement this functionality for multi-payload enums
as well, which requires adding new runtime metadata.

Example:

(swift) enum Color { case Red, Green, Blue(Int) }
(swift) print(Color.Red)
REPL.Color.Red
(swift) print(Color.Blue(5))
REPL.Color.Blue(5)

Implements <rdar://problem/18334936>.

889b8d3826 IRGen: Fix implementation of emitValueCaseTest for multi-payload enums.
Empty cases are packed into the payload under a minimal number of tags, instead of having once case per tag, as for payload cases.

350248dae5 Reorganize the directory structure under 'stdlib'
The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.

See stdlib/{public,internal,private}/README.txt for more information.
