9c52dc6c34 Change the implementation of statistic to not need destructors at all. 
Instead, the stat info is printed when llvm_shutdown() is called.
These also don't need static ctors, but getting rid of them is uglier:
still investigating.  This reduces the number of static dtors in llvm from
~1400 to ~750.

19cb81393d For PR950: 
Remove the getMaxValue and getMinValue functions from ConstantIntegral.
They don't make sense for a signless type. Also, for isMaxValue and
isMinValue, have the caller provided the signedness rather than obtaining
it from the constant's type.

The long awaited CAST patch. This introduces 12 new instructions into LLVM

748f1ae70b Added "DOUT" macro. This is used as a replacement for the std::cerr 
stream. It centralizes the use of std::cerr so that static c'tor/d'tors
aren't scattered around all over the place. The way to use it is like this:

       DOUT << "This is a status line: " << Var << "\n";

If "-debug" is specified, it will print. Otherwise, it'll not print. If
NDEBUG is defined, the DOUT does nothing.

25ad62d132 When SimplifySetCC was moved to the DAGCombiner, it was never removed from 
SelectionDAG and it has since bitrotted.  Remove the copy from SelectionDAG.
Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.

967d6af1d2 Merging ISD::LOAD and ISD::LOADX. Added LoadSDNode to represent load nodes. 
Chain and address ptr remains as operands. SrcValue, extending mode, extending
VT (or rather loaded VT before extension) are now instance variables of
LoadSDNode.

Introduce load / store addressing modes to represent pre- and post-indexed
load and store. Also added an additional operand offset that is only used in
post-indexed mode (i.e. base ptr += offset after load/store).

Added alignment info (not yet used) and isVolatile fields.

33c9ddc91d 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.

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

28645a15bd Take advantage of the recent improvements to the liveintervals set (tracking 
instructions which define each value#) to simplify and improve the coallescer.
In particular, this patch:

1. Implements iterative coallescing.
2. Reverts an unsafe hack from handlePhysRegDef, superceeding it with a
   better solution.
3. Implements PR865, "coallescing" away the second copy in code like:

   A = B
   ...
   B = A

This also includes changes to symbolically print registers in intervals
when possible.
