scons: Build with C++11 with LLVM >= 3.5.

Starting with llvm-3.5svn r202574, LLVM expects C+11 mode.

    [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.
