Rectifier frames use their frame descriptor to determine how much stack space to free. However, EnsureExitFrame changes the descriptor size (necessary for stack walking), causing rectifier frames to crash on return.

bug 717297 would fix this for real, in the meantime, this patch adds a new frame type that the stack walker knows how to correct for.
