    [ignition] Fix return value of delete on global lexical variables · ac0a2df3
    Adam Klein authored
    BytecodeGenerator previously assumed that any UNALLOCATED variable
    must be a global object property, but that's incorrect for global
    lexical variables declared in a different script.
    
    This patch fixes the behavior by always falling back to the runtime
    to deal with deleting UNALLOCATED variables. This is sub-optimal,
    but should be correct, and it's unclear if speed is important for
    this case.
