13a63f4b05 [interop][SwiftToCxx] incorporate argument labels into Stdlib API names in C++ 
This allows easier use and more wider API exposure from the Swift stdlib

In the future, all functions and method should incorporate argument labels, but it's not yet clear how

1629521b12 Exclude @objcImpl member impls from PrintAsObjC 
PrintAsClang was not aware of @objcImplementation. Teach it to skip over both member implementations (which are declared in handwritten headers, so printing them would be a redeclaration) and overrides (which may not be valid in a category, if e.g. they are declaring a designated initializer).

Fixes rdar://106035578.

compiler generated types so LLDB can display them nicely to users.

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.

168ef490af [cxx-interop] Disambiguate const and non-const methods consistently 
When importing a C++ struct that contains two methods that only differ in const-ness, we append `Mutating` to the name of the non-const method to make it possible to call from Swift unambiguously.

Unfortunately that logic was dependent on the order in which we import methods of a class: the `Mutating` suffix was added when another method with the same name was already imported.

This caused lookup failures, and the behavior was incorrect when the pair of methods return instances of an unsafe type: the const overload was renamed as `Unsafe` properly, but the non-const overload was not renamed.

28af8bef55 [interop][SwiftToCxx] make it possible to convert Swift String to a std::string in C++ 
This is done by exposing nested Index and UTF8View type in String. Nested types aren't
supported yet, so we need to employ a number of hacks to emit them.
