🚀 The feature, motivation and pitch

I found a certain set of logs to be extremely helpful in diagnosing fusion decisions.

If such logging can be added be enabled with a flag or simply in log_level.DEBUG, that would be great.

Not only should the logs be available from main scheduler decisions, but also backend codegen can_fuse decisions.

Alternatives

Writing print statements everytime one wants to debug fusion decisions.

Additional context

I can add this.
