    x86emul: mark new "cp" local var maybe-unused
    
    Just for the sake of the 32-bit build of the test harness. This wants
    reverting once unconditional uses of the variable appear (AMX, AVX10).
    
    Fixes: b20e3fbc3ec9 ("x86emul: introduce a struct cpu_policy * local in 
x86_emulate()")
