    Disable JIT compiler on SpiderMonkey 60
    
    We've had a number of segfaults in the `make javascript` test suite. The
    few times we've been able to get core dumps all appear to indicate
    something wrong in the JIT compiler. Disabling the JIT compilers appears
    to prevent these segfaults.
