I've created blueprints for the libav missed optimisations and added references to Ramana's page at: https://wiki.linaro.org/RamanaRadhakrishnan/Sandbox/RRQ112ConnectLibavgcc46R...
Those that are new and in progress I've assigned to the relevant person. Ulrich, I couldn't find a end of loop counter blueprint so I created a new one.
