The next problem is that the forward propagation assumes that propagating of

though I cannot prove it without honza's patch in.

Actually it was not honza's patch which causes the missed optimization right away.
CCP is not propagating of the second ADDR_EXPR after it became invariant.

New testcase without inlining enabled: 

One more thing if we disable ccp and DOM, we still get an ICE as now
forward propagation is doing all the work and we now know that we have
to fix the ICE also in forward propagation and not just the missed
optimization in ccp.

Thanks,
