The graph assembler calls MergeControlToEnd as part of Unreachable
node creation; this causes issues when used inside the GraphReducer
framework, since the reducer is not notified by gasm that the end node
should be revisited.
The (hacky) fix in this CL is to always mark the end node for
revisitation after a gasm reduction has taken place.
