ART: Optimize array accesses

Optimize computation of the data offset of arrays by adding
a constant for the array payload field offset, and templatized
versions of the computation. Add a correctness check on runtime
creation.

Templatize CheckVTableHasNoDuplicates.

Decreases dex2oatd preopting of a big app from 165s to 151s.
