2a7c671e2e Put RegsForValue in the llvm namespace to avoid warnings about 
classes in the llvm namespace having members with types from
anonymous namespaces.

3df24e667f Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

f0cbcd4880 Split the SelectionDAG-building code, including the FunctionLoweringInfo 
and SelectionDAGLowering classes, out of SelectionDAGISel.cpp and put
it in a separate file, SelectionDAGBuild.cpp.
