See Options::maxPerThreadStackUsage().  For tests, we explicitly set this option to a smaller amount do that tests that overflow the stack can finish faster.

However, this option is at the JSC level, not WTF.  Actual allowed stack capacity is computed as min of Options::maxPerThreadStackUsage() and capacity reported by StackBounds.
