sorry, I don't find the metadata for "int".
ps：I will update the **createTBAANode** into **createTBAAScalarTypeNode**
according [switch from old TBAA format to the new struct-path aware TBAA
format](https://discourse.llvm.org/t/dragonegg-switch-from-old-tbaa-format-to-the-new-struct-path-aware-tbaa-format/29448)
