    …kAddressingModePattern.
    
    reassociationCanBreakAddressingModePattern tries to prevent bad add
    reassociations that would break adrressing mode patterns. This adds support for
    vscale offset addressing modes, making sure we don't break patterns that
    already exist. It does not optimize _to_ the correct addressing modes yet, but
    prevents us from optimizating _away_ from them.
