ec0c7b2427 reintroduce original (asserting) semantics of CallSite(Instruction *II) 
add instead a CallSite(Value* V) constructor that is consistent with ImmutableCallSize
and use that one in client code

068e932975 ~40% faster vector shl <4 x i32> on SSE 4.1 Larger improvements for smaller types coming in future patches. 
For:

define <2 x i64> @shl(<4 x i32> %r, <4 x i32> %a) nounwind readnone ssp {
entry:
  %shl = shl <4 x i32> %r, %a                     ; <<4 x i32>> [#uses=1]
  %tmp2 = bitcast <4 x i32> %shl to <2 x i64>     ; <<2 x i64>> [#uses=1]
  ret <2 x i64> %tmp2
}

We get:

_shl:                                   ## @shl
	pslld	$23, %xmm1
	paddd	LCPI0_0, %xmm1
	cvttps2dq	%xmm1, %xmm1
	pmulld	%xmm1, %xmm0
	ret

Instead of:

_shl:                                   ## @shl
	pshufd	$3, %xmm0, %xmm2

816457c7f3 After updating value handles for RAUW, check that no weak or tracking handles 
are still on the list.  This might happen if a CallbackVH created some new value
handles for the old value when doing RAUW.  Barf if it occurs, since it is almost
certainly a mistake.

b056152ccf The isLoadFromStackSlot and isStoreToStackSlot have no way of reporting 
subregister operands like this:

%reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8)

Make them return false when subreg operands are present. VirtRegRewriter is
making bad assumptions otherwise.

This fixes PR7713.

bb2398331b It's better to have the arrays, which would trigger the creation of stack 
protectors, to be near the stack protectors on the stack. Accomplish this by
tagging the stack object with a predicate that indicates that it would trigger
this. In the prolog-epilog inserter, assign these objects to the stack after the
stack protector but before the other objects.

66b6f7d702 Use AssertingVH for InsertedValues and InsertedPostIncValues, to verify 
that the values they refer to aren't being deleted underneath them.

Make sure these containters get cleared by clear(), which IndVarSimplify
and LSR both use before deleting instructions.

cb0f921ca4 Temporary hack to let codegen assert or generate poor code in case 
we are using AVX and no AVX version of the desired intruction is present,
this is better for incremental dev (without fallbacks it's easier to spot
what's missing). Not sure this is the best hack thought (we can also disable
all HasSSE* predicates by dinamically marking them 'false' if AVX is present)

7ae22e4471 re-commit r109220, the compile error has already been fixed 
Simplifying use_iterators by dereferencing
is not a good idea. The codebase does not depend
in this any more, and it may introduce hidden
runtime cost. If you get compile errors, please
dereference your iterator before passing to cast<>
(and friends).

Also: please consider caching the result of
operator* and reusing that instead of dereferencing
many times.
