This patch adds the following compiler frontend driver options: * -fdebug-unparse (f18 spelling: -funparse) * -fdebug-unparse-with-symbols (f18 spelling: -funparse-with-symbols) The new driver will only accept the new spelling. `f18` will accept both the original and the new spelling. A new base class for frontend actions is added: `PrescanAndSemaAction`. This is added to reduce code duplication that otherwise these new options would lead to. Implementation from * `ParseSyntaxOnlyAction::ExecutionAction` is moved to: * `PrescanAndSemaAction::BeginSourceFileAction` This implementation is now shared between: * PrescanAndSemaAction * ParseSyntaxOnlyAction * DebugUnparseAction * DebugUnparseWithSymbolsAction All tests that don't require other yet unimplemented options are updated. This way `flang-new -fc1` is used instead of `f18` when `FLANG_BUILD_NEW_DRIVER` is set to `On`. In order to facilitate this, `%flang_fc1` is added in the LIT configuration (lit.cfg.py). `asFortran` from f18.cpp is duplicated as `getBasicAsFortran` in FrontendOptions.cpp. At this stage it's hard to find a good place to share this method. I suggest that we revisit this once a switch from `f18` to `flang-new` is complete. Differential Revision: https://reviews.llvm.org/D96483
