7b4cb12a95 Combine all MC initialization routines into one. e.g. InitializeX86MCAsmInfo, 
InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

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.

561d71ce7b Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down

389cb9d8c6 During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

9286081ccc Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters. 
They mostly mirror the ArrayRef constructors, with two exceptions:
 * There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
 * There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)
