Thanks, seeing alignment info in dumps helps (I think you meant -vops rather
than -alias?).

This doesn't seem to reproduce on trunk. On gcc-5 branch, I see alignment
increasing in dom2 pass.

Specifically, the 147t.slsr dump prior to dom2 has:

  <bb 23>:
...
  vectp.10_4 = vectp.22_88;
...
  # rhs access alignment 32+0
  vect__22.11_163 = MEM[(float *)vectp.10_4];

and then 149.dom2 has:

  <bb 23>:
...
  vectp.10_4 = vectp.22_88;
...
  # rhs access alignment 128+0
  vect__22.11_163 = MEM[(float *)vectp.22_88];
