There were two bugs here: * We weren't ignoring Cast in size_up_app * An application of a non-variable wasn't being charged correct The result was that some things looked too cheap. In my case I had things like ((f x) `cast` ...) y which was given size 21 instead of 30, and this had knock-on effects elsewhere that caused some large code bloat. Test Plan: * nofib runs (todo) * validate Reviewers: simonpj, austin, bgamari, erikd Subscribers: thomie Differential Revision: https://phabricator.haskell.org/D1900 GHC Trac Issues: #11564
