Bob Wilson d561daf520 Update MachineSSAUpdater with the same changes I made for the IR-level 
SSAUpdater.  I'm going to try to refactor this to share most of the code
between them.

Chris Lattner b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

Evan Cheng 0f1cc35c65 Don't try to be cute with undef optimization here. Let ProcessImplicitDefs handle it.

Evan Cheng e156f611ab - If the reaching definition is an undef and the use is a PHI, add the implicit_def to the end of the source block. 
- When reaching value is replaced with another, update the cache as well.
