runtime: load gcControllerState.scanWork atomically in revise gcControllerState.scanWork's docs state that it must be accessed atomically during a GC cycle, but gcControllerState.revise does not do this (even when called with the heap lock held). This change makes it so that gcControllerState.revise accesses scanWork atomically and explicitly. Note that we don't update gcControllerState.revise's erroneous doc comment here because this change isn't about revise's guarantees, just about heap_scan. The comment is updated in a later change.
