    Add more primops for atomic ops on byte arrays
    
    Summary:
    Add more primops for atomic ops on byte arrays
    
    Adds the following primops:
    
     * atomicReadIntArray#
     * atomicWriteIntArray#
     * fetchSubIntArray#
     * fetchOrIntArray#
     * fetchXorIntArray#
     * fetchAndIntArray#
    
    Makes these pre-existing out-of-line primops inline:
    
     * fetchAddIntArray#
     * casIntArray#
