First off: thank you for the patch and trying to improve Clang!

Also, Clang itself already has the ability to dump information about the AST: https://godbolt.org/z/aEM53YKq9
```
`-VarDecl 0x1be884d8 <<source>:1:1, col:10> col:6 x 'int' cinit
  `-IntegerLiteral 0x1be88588 <col:10> 'int' 12
```
(and has ways to filter AST dumps so there's less information about unrelated nodes), so I also question whether this functionality is necessary under another flag. I think the existing facilities already suffice, but maybe I'm missing something?
