734503be59 X86ISD::CMP now produces a chain as well as a flag. Make that the chain 
operand of a conditional branch to allow load folding into CMP / TEST
instructions.

that will require some deep pondering.

ffc0b2663e Eliminate X86ISD::TEST, using X86ISD::CMP instead. Match X86ISD::CMP patterns 
using test, which provides nice simplifications like:

-       movl %edi, %ecx
-       andl $2, %ecx
-       cmpl $0, %ecx
+       testl $2, %edi
        je LBB1_11      #cond_next90

There are a couple of dagiselemitter deficiencies that this exposes, they will
be handled later.

2926869b4a Fix a long-standing wart in the code generator: two-address instruction lowering 
actually *removes* one of the operands, instead of just assigning both operands
the same register.  This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.

1911fd4f85 Completely rearchitect the interface between targets and the pass manager. 
This pass:

1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
   output, move all this to common code, and give targets hooks they can
   implement.
3. Commonalize the target population stuff between file emission and JIT
   emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
   paves the way for "fast -O0" stuff in the CFE later, and now LLC could
   lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
   scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
   touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
   which is now orthogonal to the fact that JIT'ing is being done.
