PR tree-optimization/22555
* tree-dfa.c (okay_component_ref_for_subvars): Do not give up,
if one structure field is an array.
* tree-ssa-alias.c (create_overlap_variables_for): Likewise.
* tree-ssa-structalias.c (create_variable_info_for): Likewise.
(get_constraint_for_component_ref): Do not assert we can not
only be accessing padding if we deal with an ARRAY_REF.
* tree-ssa-loop-ivopts.c (rewrite_use): Mark new vars in stmt
for renaming.
* tree-ssa-loop.c (pass_iv_optimize): Schedule TODO_update_ssa.
* tree-ssa-operands.c (get_expr_operands): Continue scanning
operands even if we found a subvar, but ignore VOPs in this
case.
* gcc.dg/tree-ssa/alias-3.c: New testcase.
