CoreGraphics overlay: Make most CGPoint/Size/Rect operations transparent.
Expose constructors, ==, and other operators so they can be inlined down to their underlying C struct operations. Add overlays for CG{Point,Rect,Size}Zero and CGAffineTransformIdentity as well so we avoid having to load from the opaque extern storage of the C constants. rdar://problem/20888179
