[incremental] Patch: FYI: smash types in VAR_DECL

[Tom Tromey]

I'm checking this in on the incremental-compiler branch.

We weren't smashing types and decls in a VAR_DECL's DECL_INITIAL.
This meant that we would not emit a static function in a case like
this:

    static int doit (void);

    struct table {
      int (*func) (void);
    };

    struct table functions[] =
      {
        doit,
        0
      };

    static int doit (void) { return 23; }

This patch fixes the problem and lets us get a bit closer to building
libjava.
