beam_dead: Remove uncoverable case clause in update_value_dict/3
Because the code generator (v3_codegen) would not include the same value more than once in a select_val/3 instruction and because a label can only be referenced by one select_val/3 instruction, there is no way that the correct value could already be in the gb_tree. (Even if it could happen, this change is safe because only opportunity for an optimization would be missed; incorrect code would not be generated.)
