80f38be3b8 [PrintAsClang] Fix thunks for Never funcs
Swift-to-C++ thunk printing for functions didn’t really take into account Swift’s `Never` type. This type maps to `SWIFT_NORETURN`, but it also requires other tweaks to code generation, such as omitting the `return` keyword. (Removing that requires minor changes to many tests.)

Fixes rdar://124137073.

3948a2a5d3 [interop][SwiftToCxx] annotate inline thunks with SWIFT_INLINE_THUNK
This macro applies always_inline in addition to inline. It also applies artificial, which lets debugger know that this is an artificial function. The used attribute is added in debug builds to ensure that the symbol is emitted in the binary so that LLDB can invoke it.

3b3d6c825a [interop][SwiftToCxx] Annotate emitted declarations with Clang's external_source_symbol attribute
Each emitted declaration is annotated with the external_source_symbol with its own USR, to allow Clang's indexer to recognize this declaration as a Swift declaration with a specific USR

3a9b6dce9d [interop][SwiftToCxx] add support for emitting Swift stdlib dependency in one header file
This is the default behavior. You can disable this by specifying the -clang-header-expose-decls= flag explicitly when generating the header

2132cc91d0 [interop][SwiftToCxx] do not use std::move to move the returned C++ value
move needs <utility>, which is not includable in the test SDK.
