verify_flow_info patch for bb-reorder.c

[Brad Lucier <lucier at math dot purdue dot edu>]

flow.c says:

/* This function is always defined so it can be called from the
   debugger, and it is declared extern so we don't get warnings about
   it being unused. */
void verify_flow_info			PARAMS ((void));

So the comment appears to be wrong; I don't know whether to make it extern
or fix the comment.

Either way, we need a declaration of it in bb-reorder.c to get rid of
the message:

../../gcc/bb-reorder.c:784: warning: implicit declaration of function `verify_flow_info'

	* bb-reorder.c (verify_flow_info): Declare.
