feat(profiling): add ProfilesDictionary

Open morrisonlevi opened this issue 3 weeks ago • 3 comments

What does this PR do?

This adds the ProfilesDictionary data structure, which holds deduplicated functions, mappings, and strings and gives back IDs to the inserted elements.

Motivation

This is another stepping stone for my new profiling API with long-lived functions, mappings, and strings.

Additional Notes

This is stacked on top of PR #1347.

How to test the change?

Regular testing applies, just additions here (that are currently unused).
