Starting with llvm-3.5svn r202574, LLVM expects C+11 mode.
commit f8bc17fadc8f170c1126328d203f0dab78960137
Author: Chandler Carruth <chandl...@gmail.com>

[C++11] Turn off compiler-based detection of R-value references, relying
on the fact that we now build in C++11 mode with modern compilers. This
should flush out any issues. If the build bots are happy with this, I'll
GC all the code for coping without R-value references.
