ed2ffa25a1 Forgot to remove a register from the PHI-union after I'd determined that it 
interfered with other registers.  Seems like that might be a good thing to do. :-)

650b0527a4 Checking for "zero operands" during the "CanHoistInst()" method isn't necessary 
because those with side effects will be caught by other checks in here.

Also, simplify the check for a BB in a sub loop.

fe63fb986d Implement address space attribute for LLVM pointer types. Address spaces are 
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.

7431c2ba79 Teach VMCore to constant fold shufflevectors with constant operands. 
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
	pinsrw	$0, %eax, %xmm0
	punpcklwd	%xmm0, %xmm0
	pshufd	$0, %xmm0, %xmm0
	ret

14b32e1941 - Improved v8i16 shuffle lowering. It now uses pshuflw and pshufhw as much as 
possible before resorting to pextrw and pinsrw.
- Better codegen for v4i32 shuffles masquerading as v8i16 or v16i8 shuffles.
- Improves (i16 extract_vector_element 0) codegen by recognizing
  (i32 extract_vector_element 0) does not require a pextrw.

57d7d3f2d7 Move TargetData::hostIsLittleEndian out of line, which means we 
don't have to #include config.h in it.  #including config.h breaks
other projects that have their own autoconf stuff and try to #include
the llvm headers.  One obscure example is llvm-gcc.
