LegacyHTMLTreeBuilder inserts extra RenderText {#text} at (0,0) size 0x0 for newlines at end of document

Document:
<img>
</body>
</html>

(note newline after </html>)

LegacyHTMLTreeBuilder rendering tree:
  RenderBlock {HTML} at (0,0) size 800x600
    RenderBody {BODY} at (8,8) size 784x584
      RenderImage {IMG} at (0,0) size 0x0
      RenderText {#text} at (0,0) size 0x0
      RenderText {#text} at (0,0) size 0x0
      RenderText {#text} at (0,0) size 0x0

HTML5 HTMLTreeBuilder rendering tree:
  RenderBlock {HTML} at (0,0) size 800x600
    RenderBody {BODY} at (8,8) size 784x584
      RenderImage {IMG} at (0,0) size 0x0
      RenderText {#text} at (0,0) size 0x0

This affects several hundred tests.

I suspect the HTML5 tree builder is immune to this because it has code to coalesce text nodes

Eric fixed this in another bug.
