Frontend: Suppress some unsupported option warnings when verifying interfaces.

The following warnings get emitted every time we build the compiler libraries
that are implemented in Swift:

```
<unknown>:0: warning: ignoring -allow-non-resilient-access (overriden by -compile-module-from-interface or -typecheck-module-from-interface)
<unknown>:0: warning: ignoring -package-cmo (requires -allow-non-resilient-access)
<unknown>:0: warning: ignoring -allow-non-resilient-access (overriden by -compile-module-from-interface or -typecheck-module-from-interface)
<unknown>:0: warning: ignoring -package-cmo (requires -allow-non-resilient-access)
```

These warnings are generated because `-allow-non-resilient-access` and
`-package-cmo` are being passed in with `-Xfrontend` and are therefore copied
into the interface verification jobs, even though they don't apply. Suppress
the warnings under these circumstances; they aren't going to help anyone
understand a problem, so they're just spam.
