enabled with PGO



==Progress===

* Debugged the LTO failures for some time this week - not much progress.
* The bootstrap failure with trunk turned out to be the same problem
as with the CFG not being updated properly with some of the
shrink-wrap patches from Alan M . This was fixed on trunk later on
Monday.
* Tested atomics fixes but the test results are overall looking ugly .
Need to do some more debugging. Discovered GDB was broken for single
stepping in ARM atomic sequences - Filed bug report
https://bugs.launchpad.net/gdb-linaro/+bug/892008 here.
* Looked into the vmul / vmla issue for a bit - did some experiments.
Need to write these up and follow up .

=== Plans ===

* Commit the vcvt fixed point patch.
* Finish experiments with the vmla stuff and find out more about this.
* Finish debugging the LTO failures with PGO bootstrap.
* Some research into the O3 perf issues.

Absences.

* Dec 19 - 31st Dec - Tentatively booked
