    tree-optimization/115199 - fix PTA constraint processing for &ANYTHING =
LHS

    When processing a &ANYTHING =3D X constraint we treat it as *ANYTHING =
=3D X
    during constraint processing but then end up recording it as
    &ANYTHING =3D X anyway, breaking constraint graph building.  This is
    because we only update the local copy of the LHS and not the constraint
    itself.

            PR tree-optimization/115199
            * tree-ssa-structalias.cc (process_constraint): Also
            record &ANYTHING =3D X as *ANYTING =3D X in the end.

            * gcc.dg/torture/pr115199.c: New testcase.=
