VMMaker 4.3.11

Adopt TAssignmentNode>>emitCCodeOn:level:generator: from oscog for proper code generation of ifTrue:ifFalse assigned to a variable.

Reference Mantis 7455: VM overwrites extraVmMemory value with junk on 64 bit image.

For a 64-bit image, the file header may include large machine addresses and thus is stored as 16 words of size 64 (not 32). Change #writeImageFileIO: to produce header size 128 for 64-bit images.

The SystemTracer already handles this properly, but the VM proper has had this bug for some time. It causes no functional problems but could become an issue as StackInterpreter makes use of additional header fields.
