Description

Problem*

Before #4240 we needed mem2reg to be run as to not panic when fetching slice lengths.

Summary*

After the linked PR we have an improved startegy for tracking slice capacities by generating a slice capacities map before merging of values. This should enable us to remove a mem2reg pass that is run before flattening.

Additional Context

Documentation*

Check one:

  • No documentation needed.
  • Documentation included in this PR.
  • [Exceptional Case] 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.

Kind of surprised by this but I'll take it
