Reviewed by Filip Pizlo and Geoffrey Garen.

Source/JavaScriptCore: 

- Remove m_reentryDepth, ThreadStackType which are now obsolete.
- Replaced the reentryDepth checks with a StackBounds check.
- Added the Interpreter::StackPolicy class to compute a reasonable
  stack capacity requirement given the native stack that the
  interpreter is executing on at that time.
- Reserved an amount of JSStack space for the use of error handling
  and enable its use (using Interpreter::ErrorHandlingMode) when
  we're about to throw or report an exception.
- Interpreter::StackPolicy also allows more native stack space
  to be used when in ErrorHandlingMode. This is needed in the case
  of native stack overflows.
- Fixed the parser so that it throws a StackOverflowError instead of
  a SyntaxError when it encounters a stack overflow.

Source/WebCore: 

Removed the use of ThreadStackType. Enabled the reserved JSStack space
for error processing before doing work in reportException().
