It indeed works on the 4.2 branch where the loads magically disappear with the
first may_alias pass.  Possibly because it doesn't pay attention to whether
DECL_GIMPLE_REG is set or not.

Well DECL_GIMPLE_REG was not needed for vector types before 4.3.0 :) so yes it
was ignored.

I believe the mini-pre-alias passes from honza will fix this by recomputing
addressability.

 I believe the mini-pre-alias passes from honza will fix this by recomputing
 addressability.

But this is not about recomputing addressability but instead recomputing
DECL_GIMPLE_REG_P which we don't do currently.  We could do it the same time as
we recompute addressability and I think we should.  I will go look into this
futher later today.
