If the decision is taken to remove -fweb, please give me a heads-up as I have a

to facilitate the removal; just let me know.
Thanks!

Hi,
enabling -fpeel-loops with -O3 and -Ofast had unexpected effect of enabling
-fweb and -frename-registers. This patch drop -fweb from list of passes that
are implied by -fpeel-loops because it is no longer needed since we do peeling
at tree instead of RTL and the out-of-ssa pass cares about thi
