This patch fixes a bug is in tree-eh.c. IS_UNKNOWN_LOCATION is
mistakenly used, thus
the block info for a call stmt is cleared.

Bootstrapped and gcc regression testing is on-going.

Is it okay for trunk?


        tree-eh.c (lower_try_finally_dup_block): Use correct way to
        check unknown location.
