CoreGraphics overlay: Make most CGPoint/Size/Rect operations transparent (again).
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. Recommits r28387 and addresses
rdar://problem/20888179, now that the previous commit worked around
rdar://problem/20902115.
