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.
