[flang][driver] Add the new flang compiler and frontend drivers Summary: This is the first patch implementing the new Flang driver as outlined in [1], [2] & [3]. It creates Flang driver (`flang-new`) and Flang frontend driver (`flang-new -fc1`). These will be renamed as `flang` and `flang -fc1` once the current Flang throwaway driver, `flang`, can be replaced with `flang-new`. Currently only 2 options are supported: `-help` and `--version`. `flang-new` is implemented in terms of libclangDriver, defaulting the driver mode to `FlangMode` (added to libclangDriver in [4]). This ensures that the driver runs in Flang mode regardless of the name of the binary inferred from argv[0]. The design of the new Flang compiler and frontend drivers is inspired by it counterparts in Clang [3]. Currently, the new Flang compiler and frontend drivers re-use Clang libraries: clangBasic, clangDriver and clangFrontend. To identify Flang options, this patch adds FlangOption/FC1Option enums. Driver::printHelp is updated so that `flang-new` prints only Flang options. The new Flang driver is disabled by default. To enable it, set `-DBUILD_FLANG_NEW_DRIVER=ON` when configuring CMake and add clang to `LLVM_ENABLE_PROJECTS` (e.g. -DLLVM_ENABLE_PROJECTS=“clang;flang;mlir”).
