Subject: [PATCH] [llvm][cas] Fix OnDiskCASLoggerTest.cpp compilation on NetBSD
 (#212113)

`CAS/OnDiskCASLoggerTest.cpp` doesn't compile on NetBSD/amd64:

```
In member function `virtual void OnDiskCASLoggerTest_MultiProcess_Test::TestBody()':
llvm/unittests/CAS/OnDiskCASLoggerTest.cpp:230:19: error: reference to `Wait' is ambiguous
  230 |     auto Result = Wait(PI, /*Timeout=*/15, &Error);

   60 |   enum InitStatus { Uninitialized = 0, Wait = 1, Done = 2 };
      |                                        ^~~~
```

This patch removes the ambiguity, matching other uses.

Tested on `amd64-pc-netbsd10.1` and `x86_64-pc-linux-gnu`.

(cherry picked from commit 102f572188c5dbf89d92bf533a4bdc4fed1d89bd)
