Hi,

while playing around with inserting pass_ccp here and there in the pass
list, I put it after a pass where the loops state contained
LOOP_CLOSED_SSA.

And apparently pass_ccp does not preserve loop-closed ssa.

As a consequence, during executing the pass_ccp todos,
verify_loop_closed_ssa fails.

This patch fixes that by noting in pass_ccp that it does not preserve
loop-closed ssa.

OK for trunk if bootstrap and reg-test succeeds?

OK.
