[PATCH][PUSHED] options: fix ASAN issue during saving of opt. options

[Martin Liška]

Fix an obvious issue when processing save_decoded_options.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Thanks,
Martin

gcc/ChangeLog:

        * toplev.c (toplev::main): save_decoded_options[0] is program
        name and so it should be skipped.
