Add support for option -J/-module-dir in the new Flang driver. This
will allow for including module files in other directories, as the
default search path is currently the working folder. This also provides
an option of storing the output module in the specified folder.

Make the #include "file" preprocessing directive begin its
search in the same directory as the file containing the directive,
as other preprocessors and our Fortran INCLUDE statement do.
Avoid current working directory for all source files except the original.
Resolve tests.

Add support for option -I in the new Flang driver. This will allow for
included headers and module files in other directories, as the default
search path is currently the working folder. The behaviour of this is
consistent with the current f18 driver, where the current folder (i.e.
".") has the highest priority followed by the order of '-I's taking
priority from first to last.
Summary of changes:
- Add SearchDirectoriesFromDashI to PreprocessorOptions, to be forwarded
into the parser's searchDirectories
- Add header files and non-functional module files to be used in
regression tests. The module files are just text files and are used to
demonstrated that paths specified with `-I` are taken into account when
searching for .mod files.
