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.

  return (VSInt16)((vSInt16)_mm_set1_epi16(6518));
}

into:

_t3:
	movaps	LCPI1_0, %xmm0
	ret

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

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.

1eff70451f Fix PR1836: in the interpreter, read and write apints 
using the minimum possible number of bytes.  For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before.  For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness).  Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this.  Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

80a75bfae9 Adding a collector name attribute to Function in the IR. These 
methods are new to Function:

  bool hasCollector() const;
  const std::string &getCollector() const;
  void setCollector(const std::string &);
  void clearCollector();

The assembly representation is as such:

  define void @f() gc "shadow-stack" { ...

The implementation uses an on-the-side table to map Functions to 
collector names, such that there is no overhead. A StringPool is 
further used to unique collector names, which are extremely
likely to be unique per process.

	ldx r2, r1, r0

	ld r0, 16(r1)

for:

  *X = __builtin_return_address(0);
}

on ppc64.

e70da20f9a implement a readme entry, compiling the code into: 
_foo:
	movl	$12, %eax
	andl	4(%esp), %eax
	movl	_array(%eax), %eax
	ret

instead of:

_foo:
	movl	4(%esp), %eax
	shrl	$2, %eax
	andl	$3, %eax
	movl	_array(,%eax,4), %eax
	ret

As it turns out, this triggers all the time, in a wide variety of
situations, for example, I see diffs like this in various programs:

-       movl    8(%eax), %eax
-       shll    $2, %eax
-       andl    $1020, %eax
-       movl    (%esi,%eax), %eax
+       movzbl  8(%eax), %eax
+       movl    (%esi,%eax,4), %eax


-       shll    $2, %edx
-       andl    $1020, %edx
-       movl    (%edi,%edx), %edx
+       andl    $255, %edx
+       movl    (%edi,%edx,4), %edx

Unfortunately, I also see stuff like this, which can be fixed in the
X86 backend:

-       andl    $85, %ebx
-       addl    _bit_count(,%ebx,4), %ebp
+       shll    $2, %ebx
+       andl    $340, %ebx
+       addl    _bit_count(%ebx), %ebp

5d84afdc83 Commit 44487 broke bootstrap of llvm-gcc-4.2. It is 
not yet clear why, but in the meantime work around the
problem by making less use of readnone/readonly info.

018f9b020b - Mark last use of a split interval as kill instead of letting spiller track it. 
This allows an important optimization to be re-enabled.
- If all uses / defs of a split interval can be folded, give the interval a
  low spill weight so it would not be picked in case spilling is needed (avoid
  pushing other intervals in the same BB to be spilled).

a3355ffb3d Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).
