Thanks, I've committed this patch.

To the llvmpipe developers:  You must now specify the RealignStack option
using function attributes, see LLVM commit r187618.  Also, if possible,
it would be nice if you could use the LLVM C API for function
attributes, since this will help reduce the chances for build breakages
in the future.

Thanks,
Tom
