Evan Wilde 30b4aa5a58 SILOptimizer: Disable invalid passes in C++-only compiler ...

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.
