Mechanically add "Type" to the end of any protocol names that don't end in "Type," "ible," or "able." Also, drop "Type" from the end of any associated type names, except for those of the *LiteralConvertible protocols. There are obvious improvements to make in some of these names, which can be handled with separate commits. Fixes <rdar://problem/17165920> Protocols `Integer` etc should get uglier names.
