  CogVM source as per VMMaker.oscog-eem.3080

Spur:
Fix bad bug in comptation of accessor depths for primitives.  The algorithm
was fooled by code which assigned through an oject accessor, e.g.
	bm := interpreterProxy arrayValueOf: (interpreterProxy stackValue: 1).
as opposed to
	bmOop := interpreterProxy stackValue: 1.
	bm := interpreterProxy arrayValueOf: bmOop.

In any case rewrite primitiveCompressToByteArray &
primitiveDecompressFromByteArray to avoid the repeated slow stack accesses.

Generate fresh src/spur64.stack code because these had a modified Monticello
package stamp.
