Try to plug some memory leaks...
...
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.

Fix support for _Bool bitfields. The issue is that the bitfield width
...
used for _Bool is not the same as the primitive width (which for _Bool
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.

Sema-based fix for PR2334. The issue is that even if the two sides of

the condidtional have compatible types, they are not necessarily the

left-hand expression; this isn't correct, but it's good enough for most
purposes.

in Sema::CheckFunctionCall:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080512/005706.html
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.

Extend vector member references to include {.hi, .lo, .e, .o} which return a
...
vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.
Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector. This is fairly convenient syntax for some insert/extract
operations.
Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Replace Sema::CheckInitializerListTypes() with a helper class (InitListChecker) that synthesizes implicit InitListExpr's when appropriate (see InitListExpr comments in Expr.h for more details). I also moved the code to SemaInit.cpp, to help reduce clutter in SemaDecl.cpp.

NOTE: This work is incomplete and still fails many tests (as a result, it isn't enabled yet). Nevertheless, I wanted to check it in so I can work on it from home.

Major rewrite/refactoring of static analysis engine. We now use
...
EvalStore/EvalLoad to handle all loads/stores from symbolic memory, allowing us
to do checks for null dereferences, etc., at any arbitrary load/store (these
were missed checks before). This also resulted in some major cleanups, some
conceptual, and others just in the structure of the code.
This temporarily introduces a regression in the test suite (null-deref-ps.c)
before I add a new LVal type for structure fields.
