Converts the results of _findAllMatchingSelectorsInText() into a simpler bag of data and
appends those new objects to the given 'resultSelectors' Array.
@param {Array.<{document:Document, lineStart:number, lineEnd:number}>} resultSelectors
@param {Array.<SelectorInfo>} selectorsToAdd
@param {!Document} sourceDoc
@param {!number} lineOffset Amount to offset all line number info by. Used if the first line
         of the parsed CSS text is not the first line of the sourceDoc.
