The aim of this patch is to be minimal to enable incremental development of the feature on the top of the tree. This patch should be an NFC when the feature is turned off. It is turned off by default and still considered as experimental. Technical details are available in the EuroLLVM Talk: http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#7 Note that the initial prototype was done by A. Sidorin et al.: http://lists.llvm.org/pipermail/cfe-dev/2015-October/045730.html Contributions to the measurements and the new version of the code: Peter Szecsi, Zoltan Gera, Daniel Krupp, Kareem Khazem. Differential Revision: https://reviews.llvm.org/D30691 llvm-svn: 326323
