a106725fc5 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.

6aff5b94ff Make BasicAliasAnalysis a normal AliasAnalysis implementation which 
does normal initialization and normal chaining. Change the default
AliasAnalysis implementation to NoAlias.

Update StandardCompileOpts.h and friends to explicitly request
BasicAliasAnalysis.

Update tests to explicitly request -basicaa.

0fdee121f7 Fix llvm-extract so that it changes the linkage of all GlobalValues to 
"external" even when doing lazy bitcode loading.  This was broken because
a function that is not materialized fails the !isDeclaration() test.

3c261b3ff8 XFAIL the test I added with vg_leak, apparently it is the first and only llc 
-filetype=obj test, and -filetype=obj leaks a few objects. Added a FIXME, we

dec8f8b802 Fix PR6875: 
This includes a patch by Roman Divacky to fix the initial crash.

Move the actual addition of passes from *PassManager::add to
*PassManager::addImpl.  That way, when adding printer passes we won't
recurse infinitely.

Finally, check to make sure that we are actually adding a FunctionPass
to a FunctionPassManager before doing a print before or after it.
Immutable passes are strange in this way because they aren't
FunctionPasses yet they can be and are added to the FunctionPassManager.
