Add column number to instantiation info (#7376)

* Add column number to instantiation info

Instantiation info left out column number for no good reason. This adds
it in as the third element of the tuple.

* Fix test that failed and added change to changelog

An assertion test failed because it was declaring a type that was
expected to be populated by instantiationInfo with the old signature.

Also added the changes to the changelog as it is a breaking change.
