    Modula-2: Add claimed command line options to lang.opt [PR108555].

    This is a partial reversion of the changes in r13-5373-g80cf2c5e8f496b.

    As observed in the PR, handling the C and Driver options in the Modula-2
    lang-specific code could be difficult to emulate; This reverts to adding
    the required options to the language-specific .opt file.

    gcc/m2/ChangeLog:

            * gm2-lang.cc (gm2_langhook_option_lang_mask): Do not claim CL_C
            or CL_DRIVER.
            (gm2_langhook_init_options): Handle options that we want to pass
            to the preprocessor.
            * lang-specs.h: Pass -B and -save-temps to regular compile lines.
            * lang.opt: Add C and Driver options that Modula-2 intercepts for
            internal use. Reorder options into two sections and to collate.
