* Type-encoding for known structs in Foundation and CoreGraphics.

* @encoding(NSRect) -> {CGRect={CGPoint=dd}{CGSize=dd}}
* @encoding(CGRect) -> {CGRect={CGPoint=dd}{CGSize=dd}}
* @encoding(NSPoint) -> {CGPoint=dd}
* @encoding(CGPoint) -> {CGPoint=dd}
* @encoding(NSSize) -> {CGSize=dd}
* @encoding(CGSize) -> {CGSize=dd}
* @encoding(NSRange) -> {_NSRange=QQ}
* @encoding(CFRange) -> {?=qq}
* @encoding(NSEdgeInsets) -> {NSEdgeInsets=dddd}
*
* Note that NSRange and CFRange are not toll-free bridged.
* You cannot pass a CFRange to +[NSValue valueWithRange:]
* as type encoding is different.
*
* We cannot enforce this using static asserts, as @encode
* is not a constexpr. It is therefore checked in
* Tests/base/KVC/type_encoding.m
