Summary
This removes (as best as our test suite touches) all uses of the implicit legacy tuple form of
CircuitInstruction
that have crept in since ea02667 (gh-8093). The changes are largely just mechanical over to the new form.Details and comments
This PR doesn't propose the deprecation of the legacy interface yet. At the very least, that should come early in the cycle for a Terra version, and we know there to be uses in downstream Qiskit projects (Aer and Experiments each have a couple of fairly minor instances) that we can mitigate first.
