Bug 22268 – rdmd does not track dependencies properly for --extra-file

$ rdmd -m64 -Isrc -w -debug -g -unittest -i --extra-file=src/module1.d --extra-file=src/module2.d --eval="/* Do nothing */" This run, while properly running the unittests in the proper modules, will generate a faulty dependency file that only contain standard library and druntime stuff. The same happens when using a module instead an --eval, in which case, only the dependency of that module are tracked properly, and the dependencies of the modules added via --extra-file remain untracked. This is a major issue as it leads rdmd to reuse cache entries when it shouldn't and run outdated code.
