Fix source-range information for Objective-C properties. Previously,

we were just getting a range covering only the property name, which is
certainly not correct (and broke token annotation, among other
things). 

Also, teach libclang about the relationship between
@synthesize/@dynamic and @property, so we get property name and
cursor-reference information for @synthesize and @dynamic.
