Possible to enforce required coverage over certain lines?

[asraa]

Description
To validate that ENVOY_BUG conditions have code coverage, is it possible to issue warnings or a make a required check that a condition is tested for success and failure by leveraging the existing coverage report?

Motivation:

• Encourages failure condition testing, especially since these are fatal in debug mode
• Ensures that Envoy can continue safely even if hitting an ENVOY_BUG condition in release mode.

Difficulties:

• With a normal coverage report, it's opaque whether the ENVOY_BUG condition passes or fails.
