#<!-- -->220243 replaced the string `linkName` on `fir.global` with a typed
`fir::LinkageAttr`, so `GlobalOp::getLinkName()` no longer exists.

It landed 46 minutes before #<!-- -->215369 was merged, and the two changes touch
disjoint sets of files: #<!-- -->220243 never touched `AddDebugInfo.cpp`, and
#<!-- -->215369 added the only `getLinkName()` call in it. They merged cleanly with
no textual conflict, and main is currently unable to build flang:

```
flang/lib/Optimizer/Transforms/AddDebugInfo.cpp:564:39: error:
  'class fir::GlobalOp' has no member named 'getLinkName';
  did you mean 'getLinkage'?
```

Use the typed accessor, matching what #<!-- -->220243 did for the same idiom in
`CUFDeviceGlobal.cpp`.

This is offered in place of reverting #<!-- -->215369 (#<!-- -->220272), since the rest of
that change is unaffected by the rename. `flang/test/Transforms` and
`flang/test/Integration` pass locally.
