Allow funcallable instances in immobile fixedobj space, part 2 of 2
* Make the primitive object contain boxed words followed by raw words.
The raw words hold machine instructions comprising the trampoline
which loads the fin-fun and jumps to it.
* Don't create a code-component that wraps the GF when installing it
into an fdefn, since the GF looks simple.
* Enable static linkage (bypassing the FDEFN)
Other funcallable instances which are not PCL instances will still
cons a new trampoline when bound globally to a function name.
