Chris Lattner 07bd69c446 bump pointer allocate LLVM IR types, since they are never deallocated.

Chris Lattner 68ef694382 stop leaking all named struct types with an empty name. Thanks 
to Benjamin Kramer for steering me in the right direction here.

Nick Lewycky e9bb9a0baa TypeMap had a destructor that destroyed the types it held. DenseMap did not, so 
destroy those types in ~LLVMContext.

Chris Lattner b1ed91f397 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.

Dale Johannesen baa5d045c9 Add X86 MMX type to bitcode and Type. 
(The Ada bindings probably need it too, but all the
obvious places to change say "do not edit this file".)

Owen Anderson 8e89e41faf 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.

Chris Lattner 13ee795c42 remove unions from LLVM IR. They are severely buggy and not 
being actively maintained, improved, or extended.

Jeffrey Yasskin a6eedc3c03 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().

Jeffrey Yasskin cd3706cd1c Re-add the Metadata.h include to LLVMContextImpl.h so that MDNode is complete 
where FoldingSet<MDNode> is instantiated.  Clang and MSVC complain; gcc
doesn't.

Owen Anderson afd0c4cd56 Factor some of the constants+context related code out into a separate header, to make LLVMContextImpl.h 
not hideous.  Also, fix some MSVC compile errors.

Daniel Dunbar 5bf72e20eb 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.
