    [liftoff] Fix missing stack move · 42b4f15a
    Clemens Backes authored
    The {operator==} on {VarState} did not check the spill offset, so when
    merging stack states, we forgot to move stack values if both source and
    destination were stack slots, but at different offsets.
    This CL fixes this by removing the {operator==}, because the semantics
    (and use) are not clear, and it's only used in one place anyway.
    The equality check was mostly redundant, so inlining it also makes the
    code smaller and faster.
