Opto: introduce phase lateExpand to expand nodes after register allocation.

Some nodes can not be expanded during matching. E.g., register allocation
might not be able to deal with the resulting pattern. To allow better
scheduling in such cases, we introduce lateExpand which runs after
register allocation. Whether and how nodes are expanded is specified
in the ad-file. See block.cpp for a detailed documentation.
