    [builtins] Add IsOffHeapSafe predicate and test · 481c21e0
    jgruber authored
    Off-heap-safety slightly differs from isolate-independence in that it
    allows external references and checks instruction-size constraints.
    
    This adds the new predicate as well as a cctest verifying it. New
    DCHECKs are introduced to document assumptions and upcoming work.
    
    Note that this breaks the --stress-off-heap-code flag. Fixes will
    follow in upcoming CLs.
