The current safety margin between the JS stack limit and the actual
boundary of the stack space reserved by the simulator can be overrun by
a large frame.
Raise this margin to 4KiB, corresponding to the "large frame" threshold.
This ensures that the stack check is executed before the frame is
allocated if the frame is larger than this margin.
