    [wasm] Check that all initial reservations succeed · c049a3bc
    Clemens Backes authored
    After allocating a new code space, we do some initial allocations in the
    new space (e.g. for the jump table). These allocations are not allowed
    to fail.
    If this in indeed what's happening in the linked bug, this CHECK will
    give fuzzers a chance to find us a reproducer.
    
    Drive-by: Introduce {WasmCodeAllocator::kUnrestrictedRegion} to remove
    magic constants.
