d80cefc1 - Do not type check lazy accessor bodies eagerly.

Do not type check lazy accessor bodies eagerly. Start chipping away at cross-file type checker performance issues by avoiding type checking of lazy property accessor bodies when the type in question is defined in a different file and the lazy property is a typed pattern. We still type check these in the file they are defined in when we go to type check the types defined within that file. Resolves rdar://problem/26894118.
