Automated g4 rollback

*** Reason for rollback ***

I can consistently make IE8 segfault after this change

*** Original change description ***

Generalize the the special handling of HR tags in
goog.editor.range.placeCursorNextTo() to better handle IMG tags and
other no-child-allowed Element nodes. This logic now takes effect
for all browsers, rather than just IE/IE9.
The the original behavior caused scrolling issues
when inserting images or emoji in gmail, on IE.
Also change (for IE) the order
