* Commit the fix (by Chris) for a tblgen type inferencing bug.
...
* Enhanced tblgen to handle instructions which have chain operand and writes a
chain result.
* Enhanced tblgen to handle instructions which produces no results. Part of
the change is a temporary hack which relies on instruction property (e.g.
isReturn, isBranch). The proper fix would be to change the .td syntax to
separate results dag from ops dag.

1. If an operation has to be int or fp and the target only supports one
int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
for patterns involving those operators, since we do not emit the code to
check for them yet. This prevents PPC from generating FP ops currently.
Also move some code around into more logical places.
