    i386 kernel __storeload_barrier: quiet gcc -Warray-bounds
    
    Use a constant input operand instead of an output operand to tell the
    compiler about __OFFSETOF_MONITORBUF.  If we tell it we are writing to
    *(u_int *)__OFFSETOF_MONITORBUF, it rightly complains, but we aren't.
    The memory clobber already covers the necessary semantics for the
    compiler.
