REPL: Substitute type parameters from outer generic structs. This makes inner structs print correctly with the default repl printing behavior, fixing <rdar://problem/13216570> and a step on the way to fixing <rdar://problem/14211671>. For the latter radar, Optional<T> printing is still hosed because of bugs printing a Slice embedded in a struct. Swift SVN r5723
