* Make it influence the behavior of the compiled rustc, rather than just the rustc build system. That is, if verify_llvm_ir=true, even manual invocations of the built rustc will verify LLVM IR. * Enable verification of LLVM IR in CI, for non-deploy and deploy-alt builds. This is similar to how LLVM assertions are handled.
