    LoongArch: gcc12: Implement option save/restore.

    LTO option streaming and target attributes both require per-function
    target configuration, which is achieved via option save/restore.

    We implement TARGET_OPTION_{SAVE,RESTORE} to switch the la_target
    context in addition to other automatically maintained option states
    (via the "Save" option property in the .opt files).

            PR target/113233

    gcc/ChangeLog:

            * config/loongarch/genopts/loongarch.opt.in: Mark options with
            the "Save" property.
            * config/loongarch/loongarch-opts.cc
            (loongarch_update_gcc_opt_status): Update the value of the
            la_target to global_options.
            * config/loongarch/loongarch-opts.h
            (loongarch_update_gcc_opt_status): Add a function declaration.
            * config/loongarch/loongarch.cc
            (loongarch_option_override_internal): Call the function
            loongarch_update_gcc_opt_status.
            (loongarch_option_save): New functions.
            (loongarch_option_restore): Likewise.
            (TARGET_OPTION_SAVE): Define macro.
            (TARGET_OPTION_RESTORE): Likewise.
            * config/loongarch/loongarch.opt: Regenerate.
