fm_predict, multi-core, random order

[lhdgriver]

when using fm_predict with -core 30, the output order is not the same as input.
It is ok if you only need auc. But when you need gauc, you can't associate label/score with uid, because the fm_predict output is random order.
You can only use -core 1 to persist order, but it is very slow.

Any improvements?
