tl;dr https://reviews.freebsd.org/D40098
The main mozilla-central/comm-central codebases (Firefox, Thunderbird, etc) have been buildable and functional with LLVM toolchains newer than the hardcoded LLVM 13 we have in bsd.gecko.mk. This diff not only enables that, but more importantly updates the WASI SDK components to enable using newer LLVM toolchains. USES=llvm controls which version to use through your ${DEFAULT_VERSIONS} setting.
As a reminder, LTO only works when the LLVM version between Rust and everything else matches exactly. Since the current Rust 1.70.0 uses LLVM 16, LTO will only work with LLVM 16 (currently only Firefox non-ESR).
Since this has a sizeable blast radius, I'm not committing any of this until we reach consensus on the maintenance plan going forward.
