    * df-problems.c (df_lr_finalize): Add recursive call to resolve lr
    problem if fast dce is able to remove any instructions.
    * dce.c (dce_process_block): Fix dump message.
This patch fixes the problem.  The comment in the patch describes the
issue.    Since this was not really a failure, it would be hard to make
this issue into a testcase.

Ok to commit?

Bootstrapped and regression tested on x86*.
