[BACKEND] Update LLVM to llvm/llvm-project@1d40fefb08e9b114687677

Upgrading LLVM repo, because we need a feature that has been
recently submitted in llvm/llvm-project#d741435d7

Changes made:
- changed the signature of `visit` method in `ConstantAnalysis` -
i.e., accepts an instance of the `ProgramPoint`.
- updated calls to `getLatticeElementFor` -i.e., accepts
an instance of the `ProgramPoint`.
- added the required last parameter to
`LLVM::DISubprogramAttr::get` - i.e., an empty `annotations`.
