This commit adds a new ValueDecl::isLocalCapture() predicate and uses it in the right places. The predicate is true if the declaration is in local context, *or* if its at the top level of the main source file and follows a 'guard' statement. Fixes <rdar://problem/23051362> / <https://bugs.swift.org/browse/SR-3528>.
