[SPARK-12096] [MLlib] remove the old constraint in word2vec
jira: https://issues.apache.org/jira/browse/SPARK-12096
word2vec now can handle much bigger vocabulary.
The old constraint vocabSize.toLong * vectorSize < Ine.max / 8 should be
removed.
new constraint is vocabSize.toLong * vectorSize < max array length (usually
a little less than Int.MaxValue)
