Original Commit Message:
 .. by reusing the regexp stack from potentially multiple nested
 irregexp activations.

 To do this, we now maintain a stack pointer in RegExpStack. This stack
 pointer is synchronized at all boundaries between generated irregexp
 code and the outside world, i.e. when entering or returning from
 irregexp code, and when calling into C functions such as GrowStack.
