----------------
Clang generally tries to avoid relying on LLVM option parsing if at all
possible. It is not thread-safe, among other things. This causes essentially
every compile to call `llvm::cl::ParseCommandLineOptions`, when previously it
would only happen if the user passed unstable -mllvm flags.
