Description Mark Lam 2013-12-23 16:39:49 PST 
1. JSStack::disableErrorStackReserve() was wrongly comparing m_end with m_useableTop.  Fixed the comparison.
2. JSStack::installTrapsAfterFrame() is wrongly overwriting the top slow of the top frame.  Fixed to start the traps at the slot below (as in at lower memory than) the top slot in the top frame.
