Remove redundant assignment.

ScopedDecl with the backpatcher, and *not* a local variable on the stack. The
value of DeclCtx gets filled in *later* by the backpatcher.

macros but doesn't expand #includes, remove comments, remove #defines
etc.

For example:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x

bbaa  bbaa

#if 1 
funclike("gar")
foo /*blah*/  bar
bar
#endif

#if 0
funclike()
#endif
----


rewrites to:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x 

/*bbaa  bbaa*/

#if 1
 "gar" "a" "gar" "b" "gar"/*funclike*//*("gar")*/
foo /*blah*/  bar
bar
#endif

#if 0
/*funclike()*/
#endif

Rename IsPointerType to LVal::IsLValType, and update CFRefCount::EvalSummary to use IsLValType when conjuring symbols for return values (this fixes a bug with an assertion firing in the analyzer when two qualified objective-c types were compared).

-identifierResolver exposes an iterator interface to get all decls through the scope chain.
-The semantic staff (checking IdentifierNamespace and Doug's checking for shadowed tags were moved out of IdentifierResolver and back into Sema. IdentifierResolver just gives an iterator for all reachable decls of an identifier.

Fix <rdar://problem/5924225> clang ObjC rewriter: objc_exception_throw declaration in preamble does not match objc/objc-exception.h.

DO NOT pre-defined __OBJC2__. The __OBJC2__ macro should only be defined when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name). In a perfect world, this defined would be named __OBJC2_RUNTIME_ABI__. Oh well.

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.

Fix <rdar://problem/5879237> clang objc rewriter: ivars not accessible in structure generated for class

Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.

as globals).

__VA_ARGS__ syntax as well as with the amazingly awesome GNU "named 
variadic macro" extension.  Allow it with the GNU syntax as well.
