IMHO it is an antipattern to have a enum value that is Default. At any given piece of code it is not clear if we have to handle Default or if has already been mapped to a concrete value. In this case in particular, only the target can do the mapping and it is nice to make sure it is always done. This deletes the two default enum values of CodeModel and uses an explicit Optional<CodeModel> when it is possible that it is unspecified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@309911 91177308-0d34-0410-b5e6-96231b3b80d8
