Summary: This is a reunification of three separate reviews D11073, D11082, D11083. Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change. This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake. Reviewers: zaks.anna, bogner, kubabrecka, chandlerc, samsonov Subscribers: jevinskie, filcab, llvm-commits Differential Revision: http://reviews.llvm.org/D11820 llvm-svn: 244948
