Driver,CodeGen: introduce support for Swift CFString layout Add a new driver level flag `-fcf-runtime-abi=` that allows one to specify the runtime ABI for CoreFoundation. This controls the language interoperability. In particular, this is relevant for generating the CFConstantString classes (primarily through the `__builtin___CFStringMakeConstantString` builtin) which construct a reference to the "CFObject"'s `isa` field. This type differs between swift 4.1 and 4.2+. Valid values for the new option include: - objc [default behaviour] - enable ObjectiveC interoperability - swift-4.1 - enable interoperability with swift 4.1 - swift-4.2 - enable interoperability with swift 4.2 - swift-5.0 - enable interoperability with swift 5.0 - swift [alias] - target the latest swift ABI Furthermore, swift 4.2+ changed the layout for the CFString when building CoreFoundation *without* ObjectiveC interoperability. In such a case, a field was added to the CFObject base type changing it from: <{ const int*, int }> to <{ uintptr_t, uintptr_t, uint64_t }>. In swift 5.0, the CFString type will be further adjusted to change the length from a uint32_t on everything but BE LP64 targets to uint64_t. Note that the default behaviour for clang remains unchanged and the new layout must be explicitly opted into via `-fcf-runtime-abi=swift*`. llvm-svn: 345222
