Issue Description:
All cases of fully enumerated switches of ported platforms should have a `#error Unsupported Platform` and fully enumerated switches of ported architecture should have a `#error Unsupported Architecture`.
If a code section has cases for all platforms or does not have a fallback case that is portable that the following deployment target macros are satisfied it should have an error case
```
DEPLOYMENT_TARGET_EMBEDDED
DEPLOYMENT_TARGET_EMBEDDED_MINI
DEPLOYMENT_TARGET_FREEBSD
DEPLOYMENT_TARGET_HPUX
DEPLOYMENT_TARGET_IPHONESIMULATOR
DEPLOYMENT_TARGET_LINUX
DEPLOYMENT_TARGET_MACOSX
DEPLOYMENT_TARGET_SOLARIS
DEPLOYMENT_TARGET_WINDOWS
```
Some patterns are currently either ignored in the unsupported case or they only emit a warning; these should be upgraded to an error. Reference https://github.com/apple/swift-corelibs-foundation/blob/master/CoreFoundation/Base.subproj/CFInternal.h#L453 for an example of what would be a fully enumerated switch that has missing elements that should be upgraded to an error.
