With this change, the following invocations will be treated as errors (multiple actions are specified): ``` $ flang-new -fc1 -E -fsyntax-only file.95 $ flang-new -fc1 -fsyntax-only -fdebug-dump-symbols file.95 ``` In the examples above it is not clear whether it is `-fsyntax-only` or the other action that is run (i.e. `-E` or `-fdebug-dump-symbols`). It makes sense to disallow such usage. This should also lead to cleaner and clearer tests (the `RUN` lines using `%flang_fc1` will only allow one action). This change means that `flang-new -fc1` and `clang -cc1` will behave differently when multiple action options are specified. As frontend drivers are mostly used by compiler developers, this shouldn't affect or confuse the compiler end-users. Also, `flang-new` and `clang` remain consistent. Tests are updated accordingly. More specifically, I've made sure that every test specifies only one action. I've also taken the opportunity to simplify "multiple-input-files.f90" a bit.
