PR ipa/59831
* g++.dg/ipa/devirt-24.C: New testcase.
* ipa-cp.c (ipa_get_indirect_edge_target_1): Give up on -fno-devirtualize;
Try to devirtualize by the knowledge of virtual table pointer given by
aggregate propagation.
* ipa-prop.c (try_make_edge_direct_virtual_call): Likewise.
ipa_print_node_jump_functions): Dump also offset that
is relevant for polymorphic calls.
(determine_known_aggregate_parts): Add arg_type parameter; use it
instead of determining the type from pointer type.
(ipa_compute_jump_functions_for_edge): Update call of
determine_known_aggregate_parts.
* gimple-fold.c (gimple_get_virt_method_for_vtable): Break out from ...
(gimple_get_virt_method_for_binfo): ... here; simplify using
vtable_pointer_value_to_vtable.
* gimple-fold.h (gimple_get_virt_method_for_vtable): Declare.
* ipa-devirt.c (subbinfo_with_vtable_at_offset): Turn OFFSET parameter
to unsigned HOST_WIDE_INT; Use vtable_pointer_value_to_vtable.
(vtable_pointer_value_to_vtable): Break out from ...; handle also
POINTER_PLUS_EXPR.
(vtable_pointer_value_to_binfo): ... here.
* ipa-utils.h (vtable_pointer_value_to_vtable): Declare.
