Annotate use by callees in MatchedSystemStructure

[serenity4]

Implements the remaining feature for #37, mapping equations/variables to callees that use them. Requires JuliaComputing/StateSelection.jl#3.

Before merge:

• Remove StateSelection PR from project & manifest once merged.

Here is what it looks like:

I also added a matched = true parameter to @code_structure so we can easily get to this visualization.

This is good for review along with the StateSelection PR, we'll see if the crash mentioned in d93598b can be reproduced in CI.

[serenity4]

CI seems fine. @Keno can you reproduce the crash by running the test suite with this PR?

[Keno]

I do see this crash locally:

  %16 = alloca [10 x i64], align 8
  %155 = insertelement <4 x ptr> poison, ptr %16, i32 0

Maybe you can work with @gbaraldi to see if you can figure out what the issue is. Otherwise I can take a look.

[Keno]

Since this is fixed on master and we didn't see it on CI anyway, I'll go ahead and merge this.
