Break up "Simplified" demangling mode (shortened demangled descriptions for the sake of displaying in UI with small areas) into more fine-grained options instead of an opaque "Simplified" option and provide a static preset of options for displaying stack traces in Xcode UI and other tools, for example. - Don't print unmangled suffixes - Don't print module names - Shorten various generic specialization descriptions as just "specialized" - Don't display long protocol conformances - Truncate where clauses - Don't display so-called "entity" types - Shorten "partial apply *" - Shorten thunk phrases - Shorten value witness phrases - Truncate archetype references rdar://problem/21753651 Swift SVN r30247
