SourceManager*'s instead of SourceManager&'s. This allows the client specify a
NULL SourceManager when using a default constructed SourceLocation. Thus the
SourceManager can be NULL when the SourceLocation's isValid() == false.

The interface to most clients of Diagnostic remains the same.
Diagnostic::Report() is overload to either accept a SourceLocation and a
SourceManager&, or neither. Thus clients that do not have a SourceManager
cannot specify a SourceLocation.

Modified TextDiagnostics* to use this new interface.
Modified the driver to not passed in SourceManager when warning about "-I-".

SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

regions of memory that have a target specific relationship, as described in the 
Embedded C Technical Report. 

This also implements the 2007-12-11-AddressSpaces test, 
which demonstrates how address space attributes can be used in LLVM IR.

In addition, this patch changes the bitcode signature for stores (in a backwards 
compatible manner), such that the pointer type, rather than the pointee type, is 
encoded. This permits type information in the pointer (e.g. address space) to be 
preserved for stores.

LangRef updates are forthcoming.

This allows us to compile:

#include <emmintrin.h>
typedef __m128i VSInt16;
typedef short vSInt16 __attribute__ ((__vector_size__ (16)));
VSInt16 t3() {
  return (VSInt16)((vSInt16)_mm_set1_epi16(6518));
}

into:

_t3:
	movaps	LCPI1_0, %xmm0
	ret

instead of:
_t3:
	movl	$6518, %eax
	movd	%eax, %xmm0
	pextrw	$0, %xmm0, %eax
	xorps	%xmm0, %xmm0
