SILGen: Fix a bug in wildcard matching in 'switch'. When we specialize the decision matrix on a pattern, we have to start with the *first* preceding wildcard, not the last. Oops. While we're here, clean things up a bit by using Optional instead of magic integer values to track the first wildcard row. Fixes <rdar://problem/17272985>. Swift SVN r19061
