x86, mem: copy_user_64.S: Support copy_to/from_user by enhanced REP MOVSB/STOSB
Support copy_to_user/copy_from_user() by enhanced REP MOVSB/STOSB.
On processors supporting enhanced REP MOVSB/STOSB, the alternative
copy_user_enhanced_fast_string function using enhanced rep movsb overrides the
original function and the fast string function.
