CogVM binaries as per VMMaker.oscog-eem.333/r2776
* Speed-up Newspeak significantly (e.g. -28% in one compile-intensive benchmark) by maintaining unpaired methods (compilations of anonymous accessors) on a linked list instead of searching the entire method zone.
* Make primitiveObjectAtPut fail if changing the header word and the new header has a different literal count. Avoids crashing the VM when inadvertently changing the header, as a Newspeak bootstrap did recently.
* Implement frameless inst var store from arguments, so e.g. Point>>setX:Y: is frameless.
* Add Cogit support for clean blocks by scanning literals looking for BlockClosures on the current method.
