Most SwiftShims were put in the swift namespace in C++ mode which broke certain things when importing them in a swift file in C++ mode. This was OK when they were only imported as part of the swift runtime but, now they are used in C++ mode both in the swift runtime and when C++ interop is enabled. This broke when C++ interop was enabled because the `Swift` module contains references to symbols in the SwiftShims headers which are built without C++ interop enabled (no "swift" namespace). But, when C++ interop is enabled, the SwiftShims headers would put everything in the swift namespace meaning the symbols couldn't be found in the global namespace. Then, the compiler would error when trying to deserialize the Swift module.
