I DO think there is at least a good attempt that could be made to get a unique
set of names for each (perhaps a stringify of the path, ala how `#line` does
it?), but I think this is a good stand-alone feature here.
One thing I MIGHT suggest anyway though is replacing the '0' with
`defined(__CLANG_REWRITTEN_INCLUDES)`, so that turning on the `#include`
version would be trivial.
I might also suggest for certain lines,
`defined(__CLANG_REWRITTEN_SYSTEM_INCLUDES)` such that only the system headers
are used from the test machine.
So that is, a system header would be:
```#if defined(__CLANG_REWRITTEN_INCLUDES) ||
defined(__CLANG_REWRITTEN_SYSTEM_INCLUDES) /* vector expanded by
-frewrite-includes */```
