[RS4GC] Clamp UseDeoptBundles to true and update tests The full diff for the test directory may be hard to read because of the filename clash; so here's all that happened as far as the tests are concerned: ``` cd test/Transforms/RewriteStatepointsForGC git rm *ll git mv deopt-bundles/* ./ rmdir deopt-bundles find . -name '*.ll' | xargs gsed -i 's/-rs4gc-use-deopt-bundles //g' ``` llvm-svn: 259129

[PM] port Rewrite Statepoints For GC to the new pass manager. Summary: The port is nearly straightforward. The only complication is related to the analyses handling, since one of the analyses used in this module pass is domtree, which is a function analysis. That requires asking for the results of each function and disallows a single interface for run-on-module pass action. Decided to copy-paste the main body of this pass. Most of its code is requesting analyses anyway, so not that much of a copy-paste. The rest of the code movement is to transform all the implementation helper functions like stripNonValidData into non-member statics. Extended all the related LLVM tests with new-pass-manager use. No failures. Reviewers: sanjoy, anna, reames Reviewed By: anna Subscribers: skatkov, llvm-commits Differential Revision: https://reviews.llvm.org/D41162 llvm-svn: 320796

[SplitLandingPadPredecessors] Create a PHINode for the original landingpad only if it has some uses Summary: This patch adds a check in SplitLandingPadPredecessors to see if the original landingpad instruction has any uses. If not, we don't need to create a PHINode for it in the joint block since it's gonna be a dead code anyway. The motivation for this patch is that we found a bug that SplitLandingPadPredecessors created a PHINode of token type landingpad, which failed the verifier since PHINode can not be token type. However, the created PHINode will never be used in our code pattern. This patch will workaround this bug, and we might add supports in SplitLandingPadPredecessors to handle token type landingpad with uses in the future.
