it fixes PR2204.  Not too much to say about the implementation; it works 
in a similar way to the vector size attribute.

At some point, we need to modify the targets to provide information 
about the appropriate types.

Revert r51498: http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Sema/SemaDecl.cpp?rev=51498&r1=51497&r2=51498&view=diff

Turns out that there are multiple places where a redefinition diagnostic can be emitted.  A cleaner solution (without touching Sema) is to have
the Driver turn off these diagnostics.  (will submit this patch soon)

use its own enum for visibility types instead of using
llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

in Sema, per discussion on mailing list.  This doesn't cause any changes 
in the test results.  I'll probably add some more tests at some point, 
but it's an open question what we need to accept to be compatible with 
real code.

This doesn't touch the existing isConstantExpr method on Expr; that 
should be addressed somehow eventually (either removed or refined to 
whatever is appropriate).

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.

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.

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.

The expected immediate usage is in *mmintrin.h, so that they don't

shuffle builtins.

-identifierResolver exposes an iterator interface to get all decls through the scope chain.

vector of the same element type and half the width, with the high, low, even,

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.
