If the constraints field of the model has a more efficient copy_to than adding constraints one by one (e.g. SparseMatrixCSC) then even if it's behind layers of bridges, CachingOptimizer and UniversalFallback, it should be copied (if not bridged), not added one by one.
This PR addresses that.

  • Bridge layer
  • Tests
  • Find out what to do with unsupported attributes

See #1261

Requires #1267

I don't believe this will provide any gain yet but once we have #1287, it will allow efficient copy_to to go thrown to the matrix cache if the affine constraints are not bridged.
