- Add recoverable error describing that support for maximum_operations_per_instruction > 1 is experimental, and that the line number information may be incorrect.
- Bring back an error for maximum_operations_per_instruction = 0, and upgrade that error message from "not supported", to "invalid".
- This replaces the MaxOpsPerInstFixture with two explicit test cases for maximum_operations_per_instruction = 0. I could not reuse that fixture for maximum_operations_per_instruction > 1, since the advance would be done with MaxOpsPerInst > 1 so the existing expects in the fixture would fail.
