1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST.

2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl.

3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind.

3) FunctionDecl::Destroy now releases its Body using its Destroy method.

4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors.  We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes.

5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided.

is 1 bit).  The load and store changes add some casts to make the 
types consistent.  The EmitLValue changes make sure that the pointer is 
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything 
right depends on actually laying out structs in an ABI-compliant way.

the condidtional have compatible types, they are not necessarily the 
same type.  Therefore, we cast to the composite type.  As a hack, for 
the moment we assume that the composite type is the type of the 
left-hand expression; this isn't correct, but it's good enough for most 
purposes.

Partitioned BugTypeCachedLocation::isCached() into two methods: one that accepts and ExplodedNode, and the other that accepts a ProgramPoint.  The default behavior is to cache bug reports by the
location they occur (the end node).  Subclasses can override this behavior by providing a different ProgramPoint.

The bug was that the logic from the helper methods used by CheckFunctionCall
were being inverted (a subtle bug).  This would cause the parser to discard
any valid AST nodes involving several builtins (see patch).

This removes the last regression failure I'm seeing in the test suite: Analysis-Apple/NoReturn.

many test cases to fail (there is still a test case in the Analysis directory
that is failing):
