Description

Problem*

Resolves #2099 and the issue in #1954, although #2099 is now failing with another error that looks to require #2106.

Summary*

When resetting the mapping of the condition value during flattening, we were mapping it to its old value directly, rather than the value it was previously mapped to. This had the effect of forgetting any previous mappings which made it possible for (among other things) block parameters of previously deleted blocks to remain in the code.

Documentation

  • This PR requires documentation updates when merged.

    • I will submit a noir-lang/docs PR.
    • I will request for and support Dev Rel's help in documenting this PR.

Additional Context

CC @TomAFrench since this unblocks his PR.

PR Checklist*

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

This looks like it unblocks #1981 as well so thank you again Jake!
