Changes in directory llvm/lib/Transforms/IPO:

Inliner.cpp updated: 1.28 -> 1.29
Log message:

Change the callgraph representation to store the callsite along with the
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827: http://llvm.org/PR827  and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll
