1. Add GA to test BreakIterator under LSTM configuration (remove Thai
and Burmese dictionary and include Thai and Burmese LSTM)
2. Add LSTMDataName for the purpose of testing.
3. Add file base test code to test BreakIterator match results from test
file generated by pythong code in
https://github.com/unicode-org/lstm_word_segmentation/blob/master/segment_text.py
4. Fix a LSTMBreakEngine::divideUpDictionaryRange bug when the return value
should only contains the number of words found when the passed in foundBreaks
already contains some data.
5. Change the cintltest TestSwapData from testing thaidict to laodict so
it will not break while we filter out thaidict under the LSTM
configuration.
