optllvm broken on master?

Whoops, that's my fault; it shouldn't have slipped into the patch -- this is
required for LLVM 3.6 (which I was using to work on my ARM64 patch), but
clearly isn't backwards compatible.

I wonder what's best to do for this? Would it be correct to switch on LLVM
versions or should this be considered a bug in LLVM? (it was the only
change needed for 3.6)

I will submit a ticket to revert that line in the meantime.

Thanks!
Luke
