Do you want to make this conditional on a flag? If so, you could remove this by
changing a flag, which is possible with a normal chromium CL. That way you
wouldn't be blocked on another clang roll when you want to turn this on. You
could also try turning this on in tryjobs to see how much work is left etc

Sure, how do I get access to flags from a clang plugin?

 
   // Don't check autogenerated headers.
   // Make puts them below $(builddir_name)/.../gen and geni.
   // Ninja puts them below OUTPUT_DIR/.../gen
   // Xcode has a fixed output directory for everything.
