[PATCH] D37470: [analyzer] Handle ObjC messages conservatively in CallDescription

[Gábor Horváth via Phabricator via cfe-commits]

The users of CallDescription no longer need to make sure that the called 
function is a C function. This makes the API usage easier and it conservatively 
will never match ObjC Messages. In the future, this construct might be extended 
to support overloading, ctors, dtors, messages.
