Optimize SpellChecker::GetSpellCheckMarkerUnderSelection()
Currently, this method does a linear scan over all spell check markers contained
in the text node(s) containing the selection. This takes about 0.553 ms on the
source for the "List of Australian treaties" Wikipedia page. This CL refactors
this method to instead use the newly-added
DocumentMarkerController::FirstMarkerIntersectingRange() method, which is more
efficient as it uses binary search. With this change, we now spend about
~0.02 ms in this method doing the same test.
