[Bug tree-optimization/23938] New: ssa_use_operand_d using 30 bytes in struct tree_phi_arg

[dberlin at gcc dot gnu dot org]

As far as i can telll, the only reason for this being here is to make the
iterators work.
I've attached a partial patch to remove it, but it needs some work.
I don't have time to work on it more for a while
