Description

Problem*

Resolves #9735
Resolves #9746

Summary*

This PR only changes purity in the Brillig runtime. ArraySet, IncrementRc, and DecrementRc are marked as impure if they operate on a function parameter or a global. Otherwise they are pure instructions.

Additional Context

Documentation*

Check one:

  • No documentation needed.
  • Documentation included in this PR.
  • [For Experimental Features] Documentation to be submitted in a separate PR.

PR Checklist*

  • I have tested the changes locally.
  • I have formatted the changes with Prettier and/or cargo fmt on default settings.

I've bumped this from the merge queue so that #9752 can go in. We need that to go in as it will conflict with basically anything which affects a snapshot.
