Integrate LLVM BOLT into the build scripts

What is the problem this feature will solve?
Not actually a problem - just an idea of how to improve the NodeJS platform performance.
What is the feature you are proposing to solve the problem?
LLVM BOLT is a post-link optimizer (PLO), which helps to optimize a program performance even further after PGO (which is already integrated into the NodeJS build scripts).
Recently I found an article about LLVM BOLT results on NodeJS - https://aaupov.github.io/blog/2020/10/08/bolt-nodejs (from @aaupov) . More LLVM BOLT results in different applications you can read here (BOLT is already integrated into several projects like Clang, Rustc, CPython).
I think we need to evaluate LLVM BOLT applicability to NodeJS and if it helps with performance - integrate it into the NodeJS's build scripts as it's already done for PGO.
What alternatives have you considered?
Also, Propeller could be considered as an option but I have almost no experience with this optimization approach yet.
Want to send a pull request? Probably easier to discuss that way.
I am not familiar (yet) with NodeJS build infrastructure so for me right now it could be quite difficult to properly integrate LLVM BOLT into the build scripts.
Now the issue can be considered like a performance improvement idea.
