[ACTIVITY] Week ending 26th October 2018

[LLVM-203] Investigation into profiling and code-size optimizations - Collected the remaining data I needed over the weekend. - Wrote up report - Rebased patches on tip of trunk - Attached results and report to Jira issue. - A one line summary of the results is that if you are lucky you can get close to peak performance at close to Os code size if your program happens to spend most of its time in a few small places. If you are unlucky then increased inlining and unrolling can still result in an overall code size increase over -O3 but the effect will be limited.

[LLVM-158] Monitor and maintain buildbots - Relatively quiet week, a couple of patches pinged for fixes/reverts.
