Lab move complete

 - Arm machines working, network operational

 - OpenSUSE LEAP installed on D05 and QDF (via autoyast)

 - TX2 still needs some changes

OpenHPC Ansible

 - Merge done, should ask Sandia to give it a go

 - Forgot to add some options (enable_reboot / mellanox), will add later

 - New option "force_service", need a description in readme (@baptiste)

 - We need to ask other Asible users in OpenHPC to look at them

LLVM

 - 7.0 has added "unconditional branches" optimisation, reducing effect of local changes

 - Though, that opt already helps HPC applications

 - Machine pipeliner patch on https://reviews.llvm.org/D55106

 - Preparing patch for regalloc, still found more room for improvement

 - TSVC s278 has an IF that cannot be converted, even with --force-vector

 - Will try Simplify CFG or update the vectoriser if-conversion functions
