        PR target/30040
        * config/i386/driver-i386.c: Include "coretypes.h" and "tm.h".
        (bit_SSSE3): New.
        (host_detect_local_cpu): Check -mtune= vs. -march=. Rewrite
        processor detection.

        * config/i386/i386.h (CC1_CPU_SPEC): Add -mtune=native for
        -march=native if there is no -mtune=*.

        * config/i386/x-i386 (driver-i386.o): Also depend on $(TM_H)
        coretypes.h.
