    [runtime] fix ClusterFuzz regressions (and remaining nits) in CloneObject · d6efcbf0
    Caitlin Potter authored
    Includes fixes for several ClusterFuzz regressions:
    
    1) fix an invalid Handle-cast in ic.cc (chromium:866282)
    
    2) fix for improper accounting of used/unused inobject
    fields, found by clusterfuzz (chromium:866357).
    
    3) fix number of control outputs for the JSCloneObject
    operator to be used by IfSuccess and IfException nodes (chromium:866727).
    
    4) fix property constness in out-of-object properties of fast-cloned
    object to be compatible with DCHECKs in StoreIC (chromium:866861).
    
    Also includes the fixups missing from the initial commit, and
    regression tests
