Add arg_begin() and arg_end() to CallInst and InvokeInst; NFCI

 - This simplifies the CallSite class, arg_begin / arg_end are now
   simple wrapper getters.

 - In several places, we were creating CallSite instances solely to call
   arg_begin and arg_end.  With this change, that's no longer required.
