Fixed a bug in the processing of the
br_table_cache
opcode that caused out-of-range references when the label index was greater than the length of the label.The WebAssembly Specification dictates that when executing the br_table instruction, if the label index exceeds the length of the label, it should be assigned the length of the label.
