[TCWG-1424] Investigation into profile guided information for code size
- Wrote script to process all the data from all the runs and correlate
it with code size.
- Now have some visualisations of some of the data that I can use to
make sense of the output.
- Next step is to prepare a presentation for the Connect hacking room
on the output.

- Jira sweep for TCWG LLVM epics in preparation for upcoming connect.
- Presentation for Linaro connect on Clang Tooling accepted, a
bittersweet moment as I've got to write it now.
