Good question!  Given the different tradeoffs, that seems workable.
Another possibility would be to use a different TC7 for native
procedures.  After all, the only calls we need to make cheaply are
native->native and bytecode->bytecode, and the rest can go through a
general dispatch loop (possibly with inline caching).  WDYT?  (Also note
that RTL words are 32 bits wide, which may or may not be sufficient for
native code pointers.)
