I don't think this is the right approach to fix this: If llvm.threadlocal.address is used, then we need to hoist that call. Skipping it would defeat the point.

However ... I think this entire pass may just be useless how? Since we switched to using llvm.threadlocal.address, I believe that normal EarlyCSE/GVN and LICM will already perform the optimization this pass is intended to do. Maybe we can just delete this code entirely?
