  -----------
  CogVM source as per VMMaker.oscog-eem.3025

Cogit: Fix a bad slip with SPReg ~= NativeSPReg platforms (ARMv8) and FastCCall
primitives. The NativeSPReg must be restored to CStackPointer after calling the
primitive/calling checkForAndFollowForwardedPrimitiveState, otherwise an OS
interrupt will call whereever the NativeSPReg was left and the Smalltalk stack
will be damaged.
