[PATCH][X86_64] Set bit_Fast_Unaligned_Load for Excavator family CPU's

[Pawar, Amit]

For latest AMD Excavator family 0x15h CPU's, it is found that by running GLIBC benchtest SSE2_Unaligned based implementations are performing faster compare to SSE2 based implementations for routines mentioned below. Based on this observation bit_Fast_Unaligned_Load flag is set for Excavator family CPU's. This makes SSE2_Unaligned implementations as default for these routines.

Routines: strcmp, strcat, strncat, stpcpy, stpncpy, strcpy, strncpy and strstr. 

Is attached patch OK for trunk ?

please suggest.

Thanks
