  -----------
  [CIR] Add support for global linkage and visibility (#141973)

This change adds support for the CIRGlobalValueInterface and attributes
for visibility and comdat to GlobalOp.

The comdat attribute isn't correctly calculated yet, but it was required
for the CIRGlobalValueInterface interface. There are also some cases
where dso_local isn't set correctly, but it is better than it was before
this change. Those issues will be addressed in a future patch.
