Hi!

This is an update on progress towards Guile 3.  In our last update, we
saw the first bits of generated code:

  https://lists.gnu.org/archive/html/guile-devel/2018-08/msg00005.html

Since then, the JIT is now feature-complete.  It can JIT-compile *all*
code in Guile, including delimited continuations, dynamic-wind, all
that.  It runs automatically, in response to a function being called a
lot.  It can also tier up from within hot loops.
