Looks good to me with a minor test update. @dblaikie?



================
Comment at: llvm/test/Transforms/LICM/sink-debuginfo-preserve.ll:9
+; CHECK-NEXT: store i32 %.lcssa, i32* getelementptr inbounds ([2 x i32], [2 x i32]* @g_390, i64 0, i64 1), align 4, !dbg !58, !tbaa !40
+; CHECK: !58 = !DILocation(line: 0, scope: !29)
+
----------------
Probably less brittle to match `!dbg [[storeLocation:![0-9]+]]` and then check `[[storeLocation]] = !DILocation(line: 0`.
