    [isolate-data] Move the StackGuard to IsolateData · ef24a565
    Jakob Gruber authored
    IsolateData guarantees a fixed root-relative offset for its contents,
    thus allowing more efficient code generation for accesses to these
    addresses. The stack limit, located within the StackGuard, is used by
    all stack checks in CSA.
    
    This CL moves the StackGuard inside IsolateData to make such efficient
    loads of the limit possible.
