Patch to fix the crash by excluding the guard page from the stack.

There is a 4kb guard page on the stack on QNX.  The current code doesn't take this into account, causing it to crash before hitting the recursion/stack guard in WTF.  Crashes multiple layout tests including large-expressions.js and regress-96526-002.js
