        Make HTML5 lexer not ASSERT when resuming partial parses
        https://bugs.webkit.org/show_bug.cgi?id=39755

        Add a test suite for partial parsing.  This test runs all our parsing
        test cases, but stops and starts the parser at every character in the
        parse stream to make sure we resume parsing properly.  Currently, a
        bunch of the test cases are commented out, but I'll comment them back
        in as I get them running.

        * html5lib/webkit-resumer-expected.txt: Added.

        Make HTML5 lexer not ASSERT when resuming partial parses
        https://bugs.webkit.org/show_bug.cgi?id=39755

        I'm working through a variation of the webkit-runner.html test suite
        that stops the parser at every character to make sure we can resume
        parsing correctly.  This patch fixes some errors caught by ASSERTs,
        which prevent the basic tests from running to completion.  There's a
        bunch more work to do, however.

        Test: html5lib/webkit-resumer.html

        (WebCore::HTMLNames::isEndTagBufferingState):
