    [wasm] Check data segments for zero-sized memory. · e3c7324a
    ahaas authored
    According to the spec data segments are allowed even if the memory size
    is zero. However, if one of the data segments has a length greater than
    0, then module instantiation should fail.
    
    I also changed the exception type in LoadDataSegments to TypeError,
    because that's the exception type for all exceptions which can happen
    during instantiation.
