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.
