Argyrios Kyrtzidis c0279a9826 Revert r109546, it broke linux build.

Nate Begeman 269a6da023 ~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
	movd	%xmm2, %eax

Argyrios Kyrtzidis 4fac280618 Merge PCHWriterDecl.cpp's isRequiredDecl and CodeGenModule::MayDeferGeneration into a new function, 
DeclIsRequiredFunctionOrFileScopedVar.

This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also
needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes.
This fixes current (and avoids future) codegen-from-PCH bugs.

Sean Callanan 7ea3501bd8 Added support for calling functions from expressions. 
Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.

Duncan Sands fd5c8329cf 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.

Jakob Stoklund Olesen 96a890a7f8 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.
