New Revision: 164e0847a59995c0e602c9e708dfb2bf41494780
URL: https://github.com/llvm/llvm-project/commit/164e0847a59995c0e602c9e708dfb2bf41494780
DIFF: https://github.com/llvm/llvm-project/commit/164e0847a59995c0e602c9e708dfb2bf41494780.diff
LOG: [SimplifyCFG] DeleteDeadBlock() already knows how to preserve DomTree
... so just ensure that we pass DomTreeUpdater it into it.
Fixes DomTree preservation for a large number of tests,
all of which are marked as such so that they do not regress.
