Tweek lower_try_finally

Found by inspection:

By separating emit_post_landing_pad from the insertion of the code 
that's to follow the landing pad, we risk another landing pad being 
dropped in between.

I don't have a test case for this.  All of the other instances are correct.

        * tree-eh.c (lower_try_finally_copy): Do lower_eh_constructs_1
        before emit_post_landing_pad.
