    [mips][wasm] Fix kWasmInstanceOffset · 4df7b0bd
    Zhao Jiazhong authored
    Currently the kWasmInstanceOffset is computed according to the reg
    a0(kWasmInstanceRegister)'s position in the frame. And according
    to Builtins::Generate_WasmCompileLazy, it's the 7th gp_regs that
    are pushed on to stack, so the index should be 6 other than 7.
    
    Since the kWasmInstanceRegister will be pushed on to stack after
    all parameter registers, so we can use it's index, which does not
    reply on which reg kWasmInstanceRegister is, and what order the
    parameter registers are pushed on to stack.
    
    So the new index is equal to the number of all parameter registers.
