Philip Reames 82374f6b8a [RewriteStatepointsForGC] Preprocess the IR to remove unreachable blocks and single entry phis ... Two related small changes: Various dominance based queries about liveness can get confused if we're talking about unreachable blocks. To avoid reasoning about such cases, just remove them before rewriting statepoints. Remove single entry phis (likely left behind by LCSSA) to reduce the number of live values. Both of these are motivated by http://reviews.llvm.org/D8674 which will be submitted shortly.
