----------------
I have a couple of concerns with this interface:
 - we seem to be stretching to cover {mangler, querydriver} with one interface, but there's no particular reason to - we never use it polymorphically.
 - the contract is very vague. If it's just "mutate flags" then some sort of generic `function<void(CompileCommand&)>` seems sufficient
 - `File` feels out-of-place - it's purely an input for the mangler. If query-driver needs an extra input, will we add that too?
 - either `CompileCommand` or filename+argv seems reasonable, providing CompileCommand+argv is confusing. 
 - the name is hard to distinguish from tooling::ArgumentsAdjuster (which is a bad interface)

The immediate problem being solved is the type of CommandMangler::SystemIncludeExtractor, right?
Can that just be `unique_function<void(vector<string>&, StringRef)>` or so? Possibly behind `using SystemIncludeExtractor = ...`.
