[MLLIB] SPARK-4846: throw a RuntimeException and give users hints to
increase the minCount
When the vocabSize*vectorSize is larger than Int.MaxValue/8, we try to
throw a RuntimeException. Because under this circumstance it would definitely
throw an OOM when allocating memory to serialize the arrays
syn0Global&syn1Global. syn0Global&syn1Global are float arrays. Serializing
them should need a byte array of more than 8*(size of syn0Global).
Also if we catch an OOM even if vocabSize*vectorSize is less than
Int.MaxValue/8, we should give users hints to increase the minCount or decrease
the vectorSize.
