There was a problem hiding this comment.
@fredreichbier here I was wondering why that's a three. The comment above talks about 2, I believe.

- add TypeCountingNode/TypeCounter that records types - write activation patterns to a file - exclude eager nodes, and SequenceNode - try to find children type combinations. - write superinstruction report to metrics/ - update dym tests to account for AnyTag
Having it in DynamicMetrics is problematic, because DM disables a number of optimized nodes to get metrics relative to the source text. For super-instructions, we want knowledge about the actual execution behavior, and possibly even already enabled super-instructions. Thus, it’s better to have to separate tools.

This PR adds a new Truffle tool to instrument all nodes, track their execution, and determine node configurations that are frequently used together.
These node configurations might benefit from being converted into a single node that reduces the interpretation overhead.
This is work by @fredreichbier.
@fredreichbier, could you please review the PR, and check whether everything looks ok for you?
This is a first version, I might still do some more cosmetic changes.
