nikic added a parent revision: D76797: [LVI] Don't use dominator tree in isValidAssumeForContext().

After D76797 <https://reviews.llvm.org/D76797> there will no longer be any uses of the dominator tree in LVI, so we can remove it as a pass dependency, and also get rid of the dominator tree enabling/disabling logic in JumpThreading.

Apart from cleaning up the code, this also clarifies LVI cache consistency, in that the LVI cache can no longer depend on whether the DT was or wasn't enabled due to pending DT updates at any given time.
