https://github.com/rust-lang/rust/issues/52694 is a miscompilation I
found in rust when it uses system llvm 5 or 6, that was fixed 5 months
ago in the llvm rust bundles. This may or may not affect clang, but
considering it was also reported to upstream llvm independently of rust,
it's better to side with caution.
It doesn't affect 3.9, and bug 1478919 got rid of the last use of clang
5 (except for clang-tidy, but that's not used to compile).
The patches come from the llvm trunk from 5 months ago, so they're
already in our clang 7 snapshots.
Windows static analysis builds are still using an old trunk, but are
stuck on bug 1427808. They're "only" for static analysis, though.
