glxgears backtrace

Hi guys. Any 3D application will segfault when using LLVM git.
I've attached the backtrace.

Here is the commit that broke it from LLVM:

79cebfb15c5f80cc8bbc7d51da9f7827424125a is the first bad commit

    [AsmPrinter] Make AsmPrinter's OutStreamer member a unique_ptr.
    
    AsmPrinter owns the OutStreamer, so an owning pointer makes sense here. Using a
    reference for this is crufty.
