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.
