For any @llvm.assume intrinsic, if there is another which dominates it and uses the same condition, then it is redundant and can be removed. While this does not alter the semantics of the @llvm.assume intrinsics, it makes subsequent handling more efficient (and the resulting IR easier to read). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219067 91177308-0d34-0410-b5e6-96231b3b80d8
