From 3c579faecef377e0047522ca1692318ea7bf03f2 Mon Sep 17 00:00:00 2001
From: "Vikram S. Adve" <vadve@cs.uiuc.edu>

Subject: [PATCH] Added a first-class representation for each call site that
 can be used in the DS graphs in DSGraph.h.  With that, the special-purpose
 class BUDataStructure::CallSite is no longer needed here.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4229 91177308-0d34-0410-b5e6-96231b3b80d8
