DAGCombine is now quite good at zapifying them.

Add an overload that supports the uint64_t interface for use by clients
that haven't been updated yet.

pabs{b,w,d} are not two address
fix extract-to-mem sse4 ops

It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

128-bit vectors need it only when SSE is on.

to return pointers instead of references, since this is always what
is needed.

Before:
_main:
        subq    $8, %rsp
        leaq    _X(%rip), %rax
        movsd   8(%rax), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret
Now:
_main:
        subq    $8, %rsp
        movsd   _X+8(%rip), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret

Notice there is another idiotic codegen issue that needs to be fixed asap:
xorl    %ecx, %ecx
movl    %ecx, %eax

initializer problem, a minor tweak to the way the
DAGISelEmitter finds load/store nodes, and a renaming of the
new PseudoSourceValue objects.

Move to getCALLSEQ_END to ensure CALLSEQ_END node produces a flag. This is consistent with the definition in td file.
