Currently this is using the macro prefix map without allowing the
---fmacro-prefix-map argument, which is arguably pretty weird... but I
don't know what would be a better way.
I think this remapping should happen with `file-prefix-map` but shouldn't
with `debug-prefix-map` (though if it happens for both it's also not too
bad) and I believe this patch is the minimum change to achieve that. I
think it makes sense to make this follow `macro-prefix-map` although I'm
not sure if this is a macro... (OTOH, __builtin_FILE isn't a macro either
so maybe it's fine?). I haven't figured out how I can allow the option in
gfortran or how do document this new behavior though (e.g. I actually don't
know what this is called in fortran...)
