The default ThinLTO pre-link pipeline does not include optimizer last extension points. Thus, when using the new LLVM pass manager & ThinLTO & sanitizers on any opt-level different from zero, the sanitizer function passes would be omitted from the pipeline. Add optimizer last extensions points manually to the pipeline, but guard registration with stage check in the case this behaviour changes in the future.
Additionally verify that the current implementation of LLVM version check (which uses lexicographic ordering) is good enough to exclude versions before LLVM 9, where the new LLVM pass manager is unsupported.
Match `@__msan_keep_going = weak_odr constant i32 1`.
use question mark operator in a few places.
cleanup more iterator usages (and other things) * Improve weird formatting by moving comment inside else-code block. * Use .any(x) instead of .find(x).is_some() on iterators. * Use .nth(x) instead of .skip(x).next() on iterators. * Simplify conditions like x + 1 <= y to x < y * Use let instead of match to get value of enum with single variant.
