The SimplifyCFG and LoopRotate passes result in verification failures when built in a compiler that is not built with Swift sources enabled. - Scope: Disables optimizers passes in C++-only compiler for bootstrapping purposes. Has no impact on full Swift compiler build. - Risk: Low. This change has no impact in build environments where a Swift compiler is available. - Reviewers: @eeckstein - Testing: PR testing -- Full PR testing fails if passes are accidentally disabled.
