* tree-ssa-structalias.c (process_constraint): Deal with
&ANYTHING on the lhs, reject all other ADDRESSOF constraints
on the lhs.
(get_constraint_for_component_ref): Assert that we don't get
ADDRESSOF constraints from the base of the reference.
Properly generate UNKNOWN_OFFSET for DEREF if needed.
(do_structure_copy): Remove special casings, treat &ANYTHING
on the lhs like DEREF.
