[flang][driver] Add support for `--target`/`--triple` This patch adds support for: * `--target` in the compiler driver (`flang-new`) * `--triple` in the frontend driver (`flang-new -fc1`) The semantics of these flags are inherited from `clangDriver`, i.e. consistent with `clang --target` and `clang -cc1 --triple`, respectively. A new structure is defined, `TargetOptions`, that will hold various Frontend options related to the target. Currently, this is mostly a placeholder that contains the target triple. In the future, it will be used for storing e.g. the CPU to tune for or the target features to enable. Additionally, the following target/triple related options are enabled [*]: `-print-effective-triple`, `-print-target-triple`. Definitions in Options.td are updated accordingly and, to facilated testing, `-emit-llvm` is added to the list of options available in `flang-new` (previously it was only enabled in `flang-new -fc1`). [*] These options were actually available before (like all other options defined in `clangDriver`), but not included in `flang-new --help`. Before this change, `flang-new` would just use `native` for defining the target, so these options were of little value. Differential Revision: https://reviews.llvm.org/D120246
