    [wasm] Store protected instructions in an OwnedVector · ce2d01bc
    Clemens Hammacher authored
    We currently store the protected instructions per code object in a
    {std::unique_ptr<std::vector<ProtectedInstructionData>>}. This wastes
    memory, because it requires two heap allocations, plus the vector might
    over-allocate (and it currently does, because it is filled dynamically
    during compilation).
    This CL changes that to store the protected instructions in an
    {OwnedVector}. This requires one copy after generating the list of
    {ProtectedInstructionData} in an {std::vector} during compilation, but
    saves memory afterwards.
