[PATCH] D57367: [DAGCombine] Do several rounds of combine for nodes using SimplifyDemandedBits.

[Nirav Davé via llvm-commits]

 I believe I only have one patch missing (anyextend of and with a constant
doesn't apply when it could) to make the dangling node removal patches
strictly improvements and thus landable. At that point we should be
converging to a local maxima in the DAG space quickly like one would hope
and we could potentially loop until no work is done while we figure out
where we fail to add nodes to the worklist in our first pass.
