<pre>
    When trying to generate the callgraph of a simple .ll fill  (from a .c / .swift) file I get the following error : unknown pass name 'dot-callgraph'

```
$ opt-13 --dot-callgraph fibo_c.ll
WARNING: You're attempting to print out a bitcode file.
This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.

opt-13: unknown pass name 'dot-callgraph'
```

I'm using LLVM 13.0.1 from the llvm apt repo
```
$ opt-13 --version                
Ubuntu LLVM version 13.0.1
  
  Optimized build.
