Hi Andrew,
I think this change is responsible for a tablgen failure in stage2 builds:
http://green.lab.llvm.org/green/job/clang-stage2-configure-Rthinlto_build/2171/ <http://green.lab.llvm.org/green/job/clang-stage2-configure-Rthinlto_build/2171/>
I reproduced the failure locally (without ThinLTO), reverted your commit, rebuilt the stage1 clang, rebuilt the stage2 llvm-tblgen tool, and found that the crash disappears when your commit is reverted.
Could you take a look?
