    [morx/kerx] Fix sanitize regression
    
    Broke in 8dcc1913a1670ede7b124f7b5b775d7ab8791386
    
    If sanitizer is left with another object, it wouldn't work.
    
    Better fix coming soon.

    [test] Enable more of aots tests (#1408)
    
    The ones commented out in this change should've be passed :/
    a closer look is needed.
