TextIterator is one of the most important class in the editing component yet it's very under-tested as exemplified by the number of security and non-security bugs we had in this class. To mitigate this issue, I'd like to expose rangeFromLocationAndLength and locationAndLengthFromRange via window.internals. This allows us to test common usage of TextIterator throughly (Source/WebKit code only use TextIterator through these two functions) and fuzz-test them.
