[PATCH] D34135: [JumpThreading] Use DT to avoid processing dead blocks

I think PR36133 could be considered a different issue.  LVI currently uses a domtree for certain queries involving llvm.assume; to make that work, the domtree would have to be up-to-date every time we call into LVI.  But we could solve that separately from the problem of dead code in LVI.
