rdar://problem/18295292 Locally scoped type declarations were previously not serialized into the module, which meant that the debugger couldn't reason about the structure of instances of those types. Introduce a new mangling for local types: [file basename MD5][counter][identifier] This allows the demangle node's data to be used directly for lookup without having to backtrack in the debugger. Local decls are now serialized into a LOCAL_TYPE_DECLS table in the module, which acts as the backing hash table for looking up [file basename MD5][counter][identifier] -> DeclID mappings. New tests: * swift-ide-test mode for testing the demangle/lookup/mangle lifecycle of a module that contains local decls * mangling * module merging with local decls Swift SVN r24426
