Barretenberg compilation time

[codygunton]

We have been working to address the time needed to compile Barretenberg (eg #572).

We have analyzed compilation using: https://github.com/aras-p/ClangBuildAnalyzer. Cloning this into cpp/ and building it there, the "magic command" to produce a build analysis is:
rm -rf build && cmake --preset clang15 -DCMAKE_CXX_FLAGS="-ftime-trace" && cmake --build --preset clang15 && ./ClangBuildAnalyzer/build/ClangBuildAnalyzer --all build artifacts && ./ClangBuildAnalyzer/build/ClangBuildAnalyzer --analyze artifacts > build-analysis

Here is the compilation analysis at the moment:

Suspected major culprits at the moment: transcript is all in a header; zeromorph is all in a header; new Univariate template parameter; use of MANY different tuple types in relations.

This is a forever issue that we return to periodcally 😄

I spent a little bit of time investigating this in February 2025. Any change (even to a comment) in bb.main would about 50s to compile on personal dev client machine. I found that about 12s of this was due to function instantiation due to constexprness of our Barrett reduction code. I believe more time should be spend on this issue. Is there a way to schedule periodic reminders for an issue?
