For dynamic features defined from a header, we synthesize a pure Clang function to check whether the feature should be enabled at runtime. Swift modules don't have capability to deserialize this clang predicate function, leading to crasher as a result. This change fixes the crasher by hiding the synthesized function to be a module internal one. rdar://164410957
