Cannot find type _Pred in this scope

Hey there.

Currently trying to build out what's on master. Using a brew installed version of llvm for it with all the path variables set. Having a bit of trouble getting the bindings to build though. Full error log is

For more information about this error, try `rustc --explain E0412`.

Wondering if someone's hit this before. I've tried looking through the repo for any definition to _Pred but have not been able to find any.

Thank you, I can reproduce the exact some build errors with Homebrew LLVM 13.0.0 on macOS.

[pragmatrix]

The current master should build now. I will add a supplemental build soon to prevent Homebrew LLVM related build errors in the future.
