I was looking at a list of Emacs' special forms, and noticed that
prog2 is implemented in C. Is there any interest in moving this to a
simple macro?
I don't have opinion about if this is worth or not, but i think is
safer to avoid the use of backquote:  prog2 could be used in an
early stage of the bootstrap.

Instead of:
+  `(prog1
+       (progn ,form1 ,form2)
+     ,@body))

Better use:
  (cons 'prog1
        (cons (list 'progn form1 form2)
