Reviewed by Yusuke Suzuki.
Changed regExpConstructorEscape() to use the StringBuilder with
OverflowPolicy::RecordOverflow.
With this, we can throw an OOME instead of crashing when an imminent overflow
is detected.
Also fixed StringBuilder::span() to be able to handle overflows for
OverflowPolicy::RecordOverflow.
