Fix memory chunk corruption for opts_obstack (PR jit/68446)
gcc/ChangeLog:
PR jit/68446
* gcc.c (driver::decode_argv): Add call to
init_opts_obstack before init_options_struct.
* opts.c (init_opts_obstack): Remove idempotency.
(init_options_struct): Replace call to init_opts_obstack
with a gcc_assert to verify that it has already been called.
* toplev.c (toplev::main): Add call to init_opts_obstack before
calls to init_options_struct.
(toplev::finalize): Move cleanup of opts_obstack next to
cleanup of save_decoded_options, clearing the latter, and
save_decoded_options_count.
