[flang][driver] Add support for `-fget-definition` This patch adds `-fget-definition` to `flang-new`. The semantics of this option are identical in both drivers. The error message in the "throwaway" driver is updated so that it matches the one from `flang-new` (which is auto-generated and cannot be changed easily). Tests are updated accordingly. A dedicated test for error handling was added: get-definition.f90 (for the sake of simplicity, getdefinition01.f90 no longer tests for errors). The `ParseFrontendArgs` function is updated so that it can return errors. This change is required in order to report invalid values following `-fget-definition`. The actual implementation of `GetDefinitionAction::ExecuteAction()` was extracted from f18.cpp (i.e. the bit that deals with `-fget-definition`). Depends on: https://reviews.llvm.org/D100556 Differential Revision: https://reviews.llvm.org/D100558

[flang] Make the frontend driver error out when requesting multiple actions 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.
