Revert "- Use a hash table to canonicalize instances/arrays to avoid having to iterate over a linear list and search for canonical instances."

This reverts commit 95a2b02a9e74714d7e9835e7af0fd85f694a4d2d.

Once the tree shaker in precompiled code is fixed to treat the constants array in a class as a hash table this CL can be re-applied.
