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

When processing a &ANYTHING = X constraint we treat it as *ANYTHING = X
during constraint processing but then end up recording it as
&ANYTHING = 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 = X as *ANYTING = X in the end.

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