fc23781906 Sema: First pass at type-checking Swift key paths. 
TODO:

- Select the KeyPath subclass corresponding to the write capability of the key path components
- Figure out an issue with unresolved solutions being chosen with contextually-typed keypaths
- Diagnostic QoI

e3046d6f75 Parsing for native keypaths. 
Use `#keyPath2` as a stand-in for the final syntax.

a5ca6ccd61 Restructure KeyPathExpr to allow more kinds of components. 
Expand the representation in anticipation of more kinds of components. NFC intended yet.

b7d17b25ba Rename -parse flag to -typecheck 
A parse-only option is needed for parse performance tracking and the
current option also includes semantic analysis.

823c24b355 [SE-0112] Rename ErrorProtocol to Error. 
This is bullet (5) of the proposed solution in SE-0112, and the last
major piece to be implemented.

9f0cec4984 SE-0062: Implement #keyPath expression. 
Implement the Objective-C #keyPath expression, which maps a sequence
of @objc property accesses to a key-path suitable for use with
Cocoa[Touch]. The implementation handles @objc properties of types
that are either @objc or can be bridged to Objective-C, including the
collections that work with key-value coding (Array/NSArray,
Dictionary/NSDictionary, Set/NSSet).

Still to come: code completion support and Fix-Its to migrate string
literal keypaths to #keyPath.

Implements the bulk of SR-1237 / rdar://problem/25710611.
