fixes https://github.com/dart-lang/dev_compiler/issues/471 Changes here are: * Analyzer now infers list/map literals * Analyzer changed how isPotentiallyMutated* APIs work, so we need to track current function * Another fix to arrow functions. We shouldn't skip generating covariant arg checks. If there were any, we use `=> { block }` form rather than `=> expr` form. R=vsm@google.com Review URL: https://codereview.chromium.org/1757343002 .
