NSKeyValueCoding: Safe-Caching for -[NSObject valueForKey:] (#445)

Browse source 
* KVC Caching Implementation

* Do not ignore struct name when comparing type encoding as NSPoint and NSSize have the same layout

* Use fast-path when using Objective-C 2

* Guard old ValueForKey function when using the fast-path

* Add basic NSKeyValueCoding tests

* Update Copyright Years

* NSKeyValueCoding+Caching: Add Versioning to IVar Slot

* safe_caching: Remove Guards

* Add type encoding helper header

* Rename geometry structs (NSRect, NSPoint, NSSize) for toll-free bridging with CoreGraphics

* Move CG struct definitions to CFCGTypes.h

* Update known struct encoding prefixes

* Windows 64-bit is LLP64 and not LP64

* Re-order to avoid complier warning
