[BACKEND] Update to llvm/llvm-project@b5cc222d7429 (#4927)

Upgrading LLVM to pick up the following changes for AMD backend:
* llvm/llvm-project#112237

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`.
