[Bug tree-optimization/30930] [4.3 Regression] vector can cause to create an extra variable, DECL_GIMPLE_REG_P not recomputed

[rguenth at gcc dot gnu dot org]

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.
