With the intrinsics patch, I notice that we don't simplify in gimple either:
_40 = VIEW_CONVERT_EXPR<__m128i>(_39);
MEM[(__m128i * {ref-all})vec_4(D)] = _40;
_60 = MEM[(const double *)vec_4(D)];
_61 =

I just looked at what gcc-4.9.1 does and it does vary:
movdqu(%rsi), %xmm1
movdqu(%rdi), %xmm0 <--
pminsd%xmm1, %xmm0 <--
pxor%xmm1, %xmm1
pmaxsd%xmm1, %xmm0
movaps%xmm0, (%rsi

We write to memory with:
(insn 10 8 11 2 (set (mem:V2DI (reg/v/f:DI 97 [ vec ]) [0 MEM[(__m128i *
