Remove the TopLevelDecls from TranslationUnit, since all of those decls are owned by the ASTContext's TranslationUnitDecl. There are definitely some leaking Decls now that I'll tackle tomorrow

that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

Do not use DenseMap because the iterator is invalidated while constructing types. After all there was a reason why std::map was used initially!

BUILT WITH WRONG VERSION OF AUTOCONF! Somebody please regenerate with an
approved version. Thanks!

llvm-svn: 62554

This requires a rebuild of 'configure' itself. I will be committing that next, but
built with the wrong version of autoconf. Somebody who has the right one, please update
it.

As a side-note, because of the way autoconf works, all built tools will link against
libffi, not just lli. If you know how to fix this, please let me know ...

 - Add Darwin_X86_CC1Tool which is shared by Darwin/x86/Compile and
   Darwin/x86/Preprocess tools.

PTH: Emitted tokens now consist of 12 bytes that are loaded used 3 32-bit loads.  This reduces user time but increases system time because of the slightly larger PTH file.  Although there is no performance win on Cocoa.h and -Eonly, overall this seems like a good step.

SDNode subclasses to keep state that requires non-trivial
destructors, however it was already effectively impossible,
since the destructor isn't actually ever called. There currently
aren't any SDNode subclasses affected by this, and in general
it's desireable to keep SDNode objects light-weight.

This eliminates the last virtual member function in the SDNode
class, so it eliminates the need for a vtable pointer, making
SDNode smaller.

uses are added to the From node while it is processing From's
use list, because of automatic local CSE. The fix is to avoid
visiting any new uses.

Fix a few places in the DAGCombiner that assumed that after
a RAUW call, the From node has no users and may be deleted.

This fixes PR3018.
