[Nate Begeman]

Changes in directory llvm/include/llvm/CodeGen:

SelectionDAGNodes.h updated: 1.23 -> 1.24
---
Log message:

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.
