// Some command-line arguments used for compiling translation units are not
// compatible with the semantics of modules or are likely to differ between
// identical modules discovered from different translation units. This test
// checks such arguments are removed from the command-lines: '-include',
// '-dwarf-debug-flag' and '-main-file-name'. Similarly, several arguments
// such as '-fmodules-cache-path=' are only relevant for implicit modules, and
// are removed to better-canonicalize the compilation.
