1.0.3.32: make-local-alien stack alignment simplification

 * treat x86-64/darwin stack like x86-64/linux rather than x86/darwin
 * remove stack-pointer saving vops as we don't need to save and
   restore the stack in order to preserve 16-byte alignment as the
   stack should already be 16-byte aligned
