ba3ddf391f bump pointer allocate LLVM IR types, since they are never deallocated.

c09ef37171 stop leaking all named struct types with an empty name. Thanks
to Benjamin Kramer for steering me in the right direction here.

1852e21701 TypeMap had a destructor that destroyed the types it held. DenseMap did not, so
destroy those types in ~LLVMContext.

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.

(The Ada bindings probably need it too, but all the
obvious places to change say "do not edit this file".)

30268be89d Clarify the ownership model of LLVMContext and Module. Namely, contexts own
modules are instantiated in them.  If the context is deleted, all of its owned
modules are also deleted.

c1dc067970 Free all Constants in ~LLVMConstantImpl. We avoid assertion failures
by dropping all references from all constants that can use other
constants before trying to destroy any of them.

I also had to free bugpoint's Module in ~BugDriver().

6316fbcb04 Convert StringMap to using StringRef for its APIs.
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.
