This changes the DEFINE_VIRT_MACHINE macro to use the common
helpers for constructing versioned symbol names and strings,
bringing greater consistency across targets.

A DEFINE_VIRT_MACHINE_AS_LATEST helper is added so that it
is not required to pass 'false' for every single historical
machine type.
