50291d09da Initial implementation of 'fence' instruction, the new C++0x-style replacement for llvm.memory.barrier. 
This is just a LangRef entry and reading/writing/memory representation; optimizer+codegen support coming soon.

0fc2a68e8f Give TargetRegisterClass a pointer to the MCRegisterClass and use it to access its data. 
This makes TargetRegisterClass slightly slower. Next step will be making contains faster.
Eventually TargetRegisterClass will be killed entirely.

0ad63a1326 Move the logic for printing the registered targets into a static 
function on the TargetRegistry. Also clean it up and use the modern LLVM
utility libraries available instead of rolling a few things manually.

6931004b83 Add an extension point to the CommandLine library where clients can 
register extra version information to be printed. This is designed to
allow those tools which link in various targets to also print those
registered targets under --version.

Currently this printing logic is embedded into the Support library
directly; a huge layering violation. This is the first step to hoisting
it out into the tools without adding lots of duplicated code.

284b502be9 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.

c9bc5a9011 Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc. 
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.

55d7fcc5f7 - Move CodeModel from a TargetMachine global option to MCCodeGenInfo. 
- 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.
