[SimplifyCFGPass] iterativelySimplifyCFG(): support lazy DomTreeUpdater

This boils down to how we deal with early-increment iterator
over function's basic blocks: not only we need to early-increment,
after that we also need to skip all the blocks
that are scheduled for removal, as per DomTreeUpdater.
