RFR 8183133: [MVT] Arraylength method handle on Q-typed array shouldn't use ArrayAccessor.lengthL(Object[])

Looks good.

In a longer term, it's feasible to use a single implementation which 
relies on Unsafe.getInt((Object)array, ARRAY_LENGTH_OFFSET) to fetch 
array length from an array of arbitrary type.
