The lowering slow path requires not only the vreg information of the instruction, but also other information such as string id, method id, etc. For each bytecode instruction, collect the various information stored in the instruction, and use the information as the input of the gate, and in the lowering stage, take out the required information from the gate. issue:https://gitee.com/openharmony/ark_js_runtime/issues/I4WQR5 Signed-off-by: wanyanglan <wanyanglan1@huawei.com> Change-Id: I42ef36554b0b88ce3e1cd0f593e8ce9e924b83e0
