This CL adds the ability to load Dart snapshot files created by sky_packager in Sky. Using a snapshot lets us transmit all the code for an app in a single blob and should improve startup time. Later CLs will make this codepath easier to use and evaluate performance. R=eseidel@chromium.org Review URL: https://codereview.chromium.org/1197133004.
