Hi Michael,

this commit broke our LNT test builders (which do not send out emails 
yet). I reverted it in 
https://llvm.org/svn/llvm-project/polly/trunk@262202. Please see for a 
failing build:

http://lab.llvm.org:8011/builders/perf-x86_64-penryn-O3-polly-fast/builds/17616

it got fixed in

Best,
Tobias
