4039313b4c Move the registered target printing in version strings completely out of
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.

The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

685a2501b2 Sketch out an CFG reconstruction mode for llvm-objdump.
- 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.

34ad6db8b9 - 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.

e696436a7e CMake: Add a new configuration option LLVM_BUILD_CLANG that's
available when Clang is found within the LLVM tree. If enabled (the
default), Clang will be built as part of LLVM. If disabled, Clang will
be skipped... and can be built by configuring a separate object
directory just for Clang. This helps break up the monolithic
LLVM+Clang project that many Clang developers use, improving
build/load times.

672b93a332 Unfortunately several files in MC are badly violating layering rule by using

59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.

1afcace3a3 Land the long talked about "type system rewrite" patch. This
patch brings numerous advantages to LLVM.  One way to look at it
is through diffstat:
 109 files changed, 3005 insertions(+), 5906 deletions(-)

Removing almost 3K lines of code is a good thing.  Other advantages
include:

1. Value::getType() is a simple load that can be CSE'd, not a mutating
   union-find operation.
2. Types a uniqued and never move once created, defining away PATypeHolder.
3. Structs can be "named" now, and their name is part of the identity that
   uniques them.  This means that the compiler doesn't merge them structurally
   which makes the IR much less confusing.
4. Now that there is no way to get a cycle in a type graph without a named
   struct type, "upreferences" go away.
5. Type refinement is completely gone, which should make LTO much MUCH faster
   in some common cases with C++ code.
6. Types are now generally immutable, so we can use "Type *" instead 
   "const Type *" everywhere.

Downsides of this patch are that it removes some functions from the C API,
so people using those will have to upgrade to (not yet added) new API.  
"LLVM 3.0" is the right time to do this.

There are still some cleanups pending after this, this patch is large enough
as-is.

ffc0e73046 Change createAsmParser to take a MCSubtargetInfo instead of triple,
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

ebdeeab812 Eliminate asm parser's dependency on TargetMachine:
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

276365dd4b Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!
