CogVm source as per VMMaker.oscog-eem.2464

Cogit Slang Reflection:
Fix nasty bug with CogAbstractInstruction computing opcodes via reflection
caused by full blocks.  We must use method allLiterals to include literals
in blocks now.  SysV is referenced only from blocks in
CogX64Compiler class>>#initialize and so with full blocks SysV was being
moved to Undeclared, causing invalid source generation for the X64 cogits.
