b58ad4e3eb Change the ActualCallees callgraph from hash_multimap<Instruction,Function> 
to std::set<std::pair<Inst,Func>> to avoid duplicate entries.

3a10f491f0 add support for prefix/suffix strings to go around GlobalValue(s) 
(which may or be function pointers) in the asmprinter. For the moment,
this changes nothing, except the IA64 backend which can use this to write:

  data8.ua  @fptr(blah__blah__mangled_function_name)

  (by setting FunctionAddrPrefix/Suffix to "@fptr(" / ")")

4034852ba9 Add ISD::UNDEF node 
Teach the SelectionDAG code how to expand and promote it
Have PPC32 LowerCallTo generate ISD::UNDEF for int arg regs used up by fp
  arguments, but not shadowing their value.  This allows us to do the right
  thing with both fixed and vararg floating point arguments.

createPromoteMemoryToRegisterPass() to be consistent with other pass
creation functions.

e0ab2218d1 Change LowerCallTo to take a boolean isVarArg argument. This is needed 
by the PowerPC backend, and probably others in the future.

0ed923c45a Now that the dead ctor is gone, nothing uses the old node mapping exported by 
cloneInto: make it an internally used mapping.

19068b431e Two fixes for the copy ctor/operator=: 
1. Make sure to clear() 'this' before adding elements to it
  2. Make sure that the leaders of the RHS EC are the leaders of the LHS EC.

b3103a3768 Rewrite this class, making the following improvements: 
1. It now actually uses tarjan's algorithm, so it is a efficient inverse
     ackerman's function for union operations, not linear time.
  2. It now stores one copy of the data in the set instead of two.
  3. It now works for elements other than pointers.
  4. It now has a more STL-like interface that exposes iterators instead
     of internal implementation details.
