Generally looks good now, two more things to consider:
1. I think we should add a comment about the default setting for the
adjuster in the ClangTool class comment
2. How do we test this? I assume all tests still run with
-fsynatx-only; I'm not sure whether there's a good way to make sure
that code generation has not been run, apart from basically making the
output directory unwritable; I'm also fine with letting this in as is,
and adding tests when we add more adjustments...
