Add FP versions of the binary operators, keeping the int and fp worlds seperate.
...
Though I have done extensive testing, it is possible that this will break
things in configs I can't test. Please let me know if this causes a problem
and I'll fix it ASAP.

Stub out the rest of the DAG Combiner. Just need to fill in the
...
select_cc bits and then wrap it in a convenience function for use with
regular select.

Last round of 2-node folds from SD.cpp. Will move on to 3 node ops such
...
as setcc and select next.

Another round of dag combiner changes. This fixes some missing XOR folds
...
as well as fixing how we replace old values with new values.

Implement a common missing fold, (add (add x, c1), c2) -> (add x, c1+c2).
...
This restores all of stanford to being identical with and without the dag
combiner with the add folding turned off in sd.cpp.

Add an option to the DAG Combiner to enable it for beta runs, and turn on
...
that option for PowerPC's beta.

Next round of DAGCombiner changes. This version now passes all the tests
...
I have run so far when run before Legalize. It still needs to pick up the
SetCC folds, and nodes that use SetCC.

Next round of DAG Combiner changes. Just need to support multiple return
...
values, and then we should be able to hook it up.

Implement first round of feedback from chris (there's still a couple things
...
left to do).

First pass at the DAG Combiner. It isn't used anywhere yet, but it should
...
be mostly functional. It currently has all folds from SelectionDAG.cpp
that do not involve a condition code.
