This fixes a hole in the "cheap" alias analysis logic implemented within the DAG builder itself, regardless of whether proper alias analysis is enabled. It now handles this pattern produced by LSR+CodeGenPrepare. %sunkaddr1 = ptrtoint * %obj to i64 %sunkaddr2 = add i64 %sunkaddr1, %lsr.iv %sunkaddr3 = inttoptr i64 %sunkaddr2 to i32* store i32 %v, i32* %sunkaddr3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168768 91177308-0d34-0410-b5e6-96231b3b80d8
