Bug 1293584 - Fix implementation of word-break:keep-all to better follow the spec. r=m_kato

Details
Attached file The reduced demo of this issue (deleted) —
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0 Build ID: 20160726073904 Steps to reproduce: See the attachment issue_demo.html. According to CSS3 spec, a CJK punctuation char, such as "，", "。", etc, should be a candidate for word break when "word-break: keep-all;" is declared. Both IE and Chrome implement "word-break: keep-all;" in this way, but Firefox does not. Actual results: The text is never wrapped at a CJK punctuation such as "，", "。", etc. Expected results: The text should be wrapped at a CJK punctuation, such as "，", "。", etc, if it exceeds the element width.
Summary: CSS "word-break: keep-all;" fails to break at CJK punctuations → CSS "word-break: keep-all;" fails to break the text at CJK punctuations
