Mark nodes to be force-rebuilt during node restarting Non-deterministic nodes may evaluate to different values after being restarted. By ensuring that the nodes are "force-rebuilt" after a restart, such a situation won't result in a crash. Because restarted nodes are no longer dirtied with isChanged=true, the assertion logic that ensures that nodes are not dirtied twice with the same value for isChanged can go back into the #markDirty method. In other words, this CL includes a logical rollback of "Permit marking dirty/changed a node more than once". This also fixes a race condition bug where a dep which is restarted by >1 parent could cause a crash if the dep was inflight when the later restart attempted to dirty it. RELNOTES: None.
