Do you need to instrument the /source code/ in particular? The usual
approach with other instrumentation (sanitizers, code coverage, etc) is
just to instrument the resulting binary (by instrumenting the LLVM IR
generated by the frontend - usually during IR generation in the frontend
(Clang, most often)) rather than mutating the source (or generating a
mutated copy of the source) & then compiling that.

The refactoring tools are really focussed on the scenario of refactoring -
where you actually want to modify the original source. (not that they can't
be used for other things, just that they might not be the best tool for the
job)
