InstCombine cannot effectively remove redundant assumptions without them registered in the assumption cache. The vectorizer can create identical assumptions but doesn't register them with the cache, resulting in slower compile times because InstCombine tries to reason about a lot more assumptions. Fix this by registering the cloned assumptions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@265800 91177308-0d34-0410-b5e6-96231b3b80d8
