ebdf389e2f Add virtual method spillCalleeSaveRegisters() and restoreCalleeSaveRegisters() 
to MRegisterInfo. These allow the target to issue instructions to spill and
restore callee saved registers in case where individual stores / loads aren't
the correct / profitable choice.

57a0342e96 For PR950: 
Add a new feature to FunctionType, Parameter Attributes. This allows tags
such as "sext" and "zext" to be associated with a faunction's arguments
or return type. This allows signedness information to be carried forward
from the frontend to the backend for arguments and result types.

ecb2768758 Refactor statistic a big and introduce a horrible-but-necessary macro 
(STATISTIC), which allows us to define statistics that don't introduce
static ctors into the .o files.  I'm migrating code over to use this
incrementally.

Introduce FPPassManager to manage function passes and
BBPassManagers.

Now FunctionPassManagerImpl is an implementation class
used by externally visible FunctionPassManager to manage
FPPassManagers.

Module pass manager (MPPassManager) now manages FPPassManagers
and ModulePasses.

691458697c Fix problems in the CBE and InstructionCombining which use the isMaxValue 
and isMinValue methods of ConstantInt. These have been broken since the
isSigned parameter was added. It is necessary to use the signed version
of the type in the call to isValueValidForType or else incorrect results
are returned.

5c7e326585 Added an automatic cast to "std::ostream*" etc. from OStream. We then can

instead, check for null, and then dispatch to the correct print() method.

975f05852d 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.

the sparc fpmover.

1ea783f13a 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.

Rename LHSBB/RHSBB to TrueBB/FalseBB.  Allow the RHS value to be null,
in which case the LHS is treated as a bool.

24446e253a 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.

02569d7355 - Added a hook processFunctionBeforeCalleeSaveScn(). This is called by PEI just 
before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.
- Modified comments. It's important to note the order of registers in the array
returns by getCalleeSaveRegs() determines the order of callee save spill 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.

differing value numbers that become identical when coallsced.  Among other
things, this fixes CodeGen/X86/shift-coalesce.ll and PR687.
