Subject: Change construction of common ObjC functions to use CGCall
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=34c94a2babcac200c8e0fd778e549afcc43e2df1;p=clang

Change construction of common ObjC functions to use CGCall
infrastructure to construct function type.
 - For consistencty, we should probably always use this to construct
   function types, but these are absolutely necessary to ensure that
   we can emit calls to these functions.
