this changes nothing, except the IA64 backend which can use this to write:

dont' regen the whole dag if unneccesary.  Second, fix and ugly bug with
the _PARTS nodes that caused legalize to produce multiples of them.
Finally, implement initial support for FABS and FNEG.  Currently FNEG is
the only one to be trusted though.

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.

LowerCallTo and ISD::CALL are going to need to be modified, regs are being

  * Stop being pessimistic about output register allocation
  * Start to handle function descriptors: compute target GPs and so on
  when doing indirect calls etc. Not there yet, though. For the moment,
  we try to use _indirect_ branches wherever possible, to stress test
  function descriptors.
  * FP divide-by-zero should work now
  * add varargs (it doesn't work, though)

At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)
