When targeting a V100, this command fails for me in both pgo1.c and pgo2.c.  In the LTO case:

```
LLVM ERROR: Circular dependency found in global variable set 
```

In the non-LTO case:

```
fatal error: error in backend: NVPTX aliasee must be a non-kernel function definition
```

I do not see this problem in PR #93365's pgo1.c.
