vmgen-related changes:
in prims2x:
Conversion macros for single items now take 2 arguments
Converting from two items to a type has changed order
argument printing for disassembler disabled (for now)
disassembler now also uses VM_IS_INST
in Gforth and vmgen-ex: adapted to work with changed prims2x
new: vmgen-ex2: uses union for Cell instead of casting (lots of
changes compared to vmgen-ex)
/* support functions for vmgen example
