    [foozzie] Always include all typed-array mocks · 6546fcf1
    Michael Achenbach authored
    Due to https://crbug.com/1195263, large typed arrays can have an
    observable difference on the same architecture, depending on
    optimization behavior.
    
    For differential fuzzing comparisons, we previously used a proxy
    for typed arrays that capped the maximum size only when comparing
    different architectures - there an observable difference is WAI.
    
    We move the capping code and make it arch-independent for now until
    the bug above gets fixed, since it caused too many duplicates, which
    degrade fuzzing performance.
