Log:
        PR c++/87554 - ICE with extern template and reference member.

The removed code ended up setting DECL_INITIAL to the INIT_EXPR returned by
split_nonconstant_init, which makes no sense.  This code was added back in
1996, so any rationale is long lost.

        * decl.c (cp_finish_decl): Don't set DECL_INITIAL of external vars.
