Spur CoInterpreter: fix crashes of vmParameterAt: on WIndows under Clang.  The PrimCallOnSmalltalkStack needs PrimCallOnSmalltalkStackAlign2x also.

  	 to forwarders, but this isn't done until failure. The primitiveMetadataTable
  	 is populated based on the primitiveMetadata: pragma in internal primitives."
