Do not create a temporary Range object on updating spell checking markers.
As these markers are conditionally updated on every edit operation,
avoid creating a temporary Range object when doing so. With Oilpan
enabled, this avoids creating a GCed object that is only delay'edly
released.
Improves Oilpan performance on blink_perf.dom.textarea-edit by 10%.
