x86, alternative, doc: Add comment for applying alternatives order
Some string operation functions may be patched twice, e.g. on enhanced REP MOVSB
/STOSB processors, memcpy is patched first by fast string alternative function,
then it is patched by enhanced REP MOVSB/STOSB alternative function.
Add comment for applying alternatives order to warn people who may change the
applying alternatives order for any reason.
