[flang][driver] Add support for `-D`, `-U` Add support for options -D and -U in the new Flang driver. Summary of changes: - Create PreprocessorOptions, to be used by the driver then translated into Fortran::parser::Options - Create CompilerInvocation::setFortranOpts to pass preprocessor options into the parser options - Add a dedicated method, Flang::AddPreprocessingOptions, to extract preprocessing options from the driver arguments into the preprocessor command arguments Macros specified like -DName will default to definition 1. When defining macros, the new driver will drop anything after an end-of-line character. This is consistent with gfortran and clang, but different to what currently f18 does. However, flang (which is a bash wrapper for f18), also drops everything after an end-of-line character. So gfortran-like behaviour felt like the natural choice. Test is added to demonstrate this behaviour. Reviewed By: awarzynski Differential Revision: https://reviews.llvm.org/D93401

! Ensure the end-of-line character and anything that follows after in a macro definition (-D) is ignored.

[flang][driver] Remove `%flang-new` from the LIT configuration `%flang-new` was introduced in the early days of the new driver to make a clear distinction between the tests for the current and the new driver. We have since introduced `%flang` (compiler driver) and `%flang_fc1` (frontend driver) as the long term solution. This has allowed us to share tests between `flang-new` and `f18`. This patch replaces all uses of `%flang-new` with `%flang` and `%flang_fc1`. Some tests are reformatted so that all tests look uniform and are easier to follow. Where possible, `! REQUIRES: new-flang-driver` is deleted so that more tests can be shared with `f18`. To facilitate this, `f{no-}implicit-none` are introduced in `f18` with semantics identical to `flang-new`. Two tests are deleted rather than updated: * flang/test/Frontend/print-preprocess-C-file.f90 * flang/test/Frontend/print-preprocessed-file.f90 Instead, there is plenty of preprocessor tests in flang/test/Preprocessing/.
