[ADCE] Fix incorrect reporting of CFG changes
This patch fixes 2 related bugs in ADCE: - `performDeadCodeElimination` does not report changes if it did ONLY CFG changes (affects both old and new pass managers); - When control flow removal is enabled, new pass manager does not drop CFG analyses. Both can lead to incorrect loop info after ADCE that does only CFG changes. Differential Revision: https://reviews.llvm.org/D78103 Reviewed By: Denis Antrushin
