With both 3.3 and trunk (I don't have a 7.0 handy; I can build it if it would be helpful):

  movaps  .LCPI0_0(%rip), %xmm0   # xmm0 = [48,49,50,51]
  movaps  .LCPI0_1(%rip), %xmm1   # xmm1 = [52,53,54,55]
  movaps  .LCPI0_2(%rip), %xmm2   # xmm2 = [56,57,97,98]
  movaps  .LCPI0_3(%rip), %xmm3   # xmm3 = [99,100,101,102]
  retq
