too!

03be4a96f3 (1) Rematerialize nodes from the globals graph into the current graph 
after all callers are inlined into the current graph.
(2) Optimize the way a graph is inlined into its callees in the TD phase:
    (a) Use DSGraph::cloneReachableSubgraph to clone only a subgraph at
        each call site, for faster inlining.
    (b) Clone separately for the same callee at different call sites,
        since only the reachable subgraph is being cloned, not the entire
        caller graph.

2d2303db22 Fix logical error in TD pass: we should clear Mod/Ref bits of each caller 
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

df307e6fd0 Implement a new mergeInGraph method, which basically factors code out of 
the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.

51a2c3cc2d - Make sure to only keep track of mappings that the TD pass may need in the 
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

f76087336f - Add "ResolvingCaller" to the CallSite record. This keeps track of which 
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

78c1e7d83c As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

5c3ce31e1f - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

dc9e142686 Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.
