This makes us able to get rid of dependencies to parser.h from places which only need the ParseInfo, and also gets rid of the curious Parser <-> Compiler circular dependency. Also IWYUd where necessary. BUG= Review-Url: https://codereview.chromium.org/2268513002 Cr-Commit-Position: refs/heads/master@{#38777}
