x86, mem: memmove_64.S: Optimize memmove by enhanced REP MOVSB/STOSB
Support memmove() by enhanced rep movsb. On processors supporting enhanced
REP MOVSB/STOSB, the alternative memmove() function using enhanced rep movsb
overrides the original function.
The patch doesn't change the backward memmove case to use enhanced rep
movsb.
