Issue Description:

Objective-C subscripting methods in the JSContext(SubscriptSupport) and JSValue(SubscriptSupport) categories aren't imported as Swift subscripts.

SwiftDeclConverter::importSubscript in lib/ClangImporter/ImportDecl.cpp is supposed to create a Swift subscript and mark the subscripting methods with @available(*, unavailable, message: "use subscripting").

The Objective-C subscript methods have to have matching types in order for Swift to turn them into a subscript. Please file a bug report against JavaScriptCore about this at https://bugreport.apple.com.
