[flang][driver] Add forced form flags and -ffixed-line-length Add support for the following layout options: * -ffree-form * -ffixed-form - -ffixed-line-length=n (alias -ffixed-line-length-n) Additionally remove options `-fno-free-form` and `-fno-fixed-form` as they were initially added to forward to gfortran but gfortran does not support these flags. This patch adds the flag FlangOnlyOption to the existing options `-ffixed-form`, `-ffree-form` and `-ffree-line-length-` in Options.td. As of commit 6a75496836ea14bcfd2f4b59d35a1cad4ac58cee, these flags are not currently forwarded to gfortran anyway. The default fixed line length in FrontendOptions is 72, based off the current default in Fortran::parser::Options. The line length cannot be set to a negative integer, or a positive integer less than 7 excluding 0, consistent with the behaviour of gfortran. This patch does not add `-ffree-line-length-n` as Fortran::parser::Options does not have a variable for free form columns. Whilst the `fixedFormColumns` variable is used in f18 for `-ffree-line-length-n`, f18 only allows `-ffree-line-length-none`/`-ffree-line-length-0` and not a user-specified value. `fixedFormcolumns` cannot be used in the new driver as it is ignored in the frontend when dealing with free form files. Summary of changes: - Remove -fno-fixed-form and -fno-free-form from Options.td - Make -ffixed-form, -ffree-form and -ffree-line-length-n FlangOnlyOption in Options.td - Create AddFortranDialectOptions method in Flang.cpp - Create FortranForm enum in FrontendOptions.h - Add fortranForm_ and fixedFormColumns_ to Fortran::frontend::FrontendOptions - Update fixed-form-test.f so that it guarantees that it fails when forced as a free form file to better facilitate testing.

! Ensure arguments -ffree-form and -ffixed-form work as expected.

[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/.
