This patch allows floop_loops_find to gather more information about
natural loops; in particular about the pre-header extended basic block
and about the loop nodes that dominate all the loop exits. I have
also added a flags option to control what information is gathered.
I've bootstrapped gcc with this patch but could someone pleae cast
their beady little eye over it in case I've overlooked something
obvious.
Thanks, Michael.
