There are two ways to map a variable to its lexical scope. Lexical scope information is embedded in MDNode describing the variable. It is also available as a part of DebugLoc attached with DBG_VALUE instruction. DebugLoc attached with an instruction is less reliable in optimized code so use information embedded in the MDNode.

Clean up includes of llvm/Analysis/ConstantFolding.h so it's included where it's used and not included where it isn't.

While emitting constant value, look through derived type and use underlying basic type to determine size and signness of the constant value.

Move the shift operator and special value (32 encoded as 0 for PKHTB) handling
into the instruction printer. This cleans up a bit of the disassembler
special casing for these instructions, more easily handles not printing the
operand at all for "lsl #0" and prepares for correct asm parsing of these
operands.

Commit LangRef changes for LLVM concurrency model.  Start of supporting C++0x memory model and atomics.  See thread on llvmdev titled "Reviving the new LLVM concurrency model".

Unbreak the MSVC build. Since the "next" function already exists in the MSVC headers, we need the explicit llvm:: qualifier to prevent a conflict.

Move common definitions for ARM and Thumb2 into ARMInstrFormats.td and rename
them to be a bit more descriptive that they're for the PKH instructions.

The shift type is implied by the instruction (PKHBT vs. PKHTB) and so shouldn't
be also encoded as part of the shift value immediate. Otherwise we're able to
represent invalid instructions, plus it needlessly complicates the
representation. Preparatory work for asm parsing of these instructions.

There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

- Not great yet, but it's a start.
- Requires an object file with a symbol table. (I really want to fix this, but it'll need a whole new algorithm)
- ELF and COFF won't work at the moment due to libObject shortcomings.

To try it out run
$ llvm-objdump -d --cfg foo.o

This will create a graphviz file for every symbol in the object file's text section containing a CFG.

- Introduce JITDefault code model. This tells targets to set different default
  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.
