Implement -rewrite-macros, which is a crazy macro expander that expands
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).

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,
