    Set index_Fast_Unaligned_Load for Excavator family CPUs

    GLIBC benchtest testcases shows SSE2_Unaligned based implementations
    are performing faster compare to SSE2 based implementations for
    routines: strcmp, strcat, strncat, stpcpy, stpncpy, strcpy, strncpy
    and strstr. Flag index_Fast_Unaligned_Load is set for Excavator family
    0x15h CPU's. This makes SSE2_Unaligned based implementations as
    default for these routines.

        [BZ #19467]
        * sysdeps/x86/cpu-features.c (init_cpu_features): Set
        index_Fast_Unaligned_Load flag for Excavator family CPUs.
